Rabba bar Nachmani (born about 270, died 330) possessed, like the family to which he belonged, certain original qualities. He was of a family from Mamal or Mamala, a city of Galilee, the inhabitants of which were for the most part descendants of Aaron, and members of the family of Eli; they asserted that they participated in the curse with which this house had been visited, and which prevented any of its members from ever attaining extreme old age. Whoever went to Mamala was astonished at seeing so many persons with black hair; a grey-haired man was a rarity.
Rabba had three brothers, whose names were Kailil, Ushaya, and Chananya; all of them lived in the greatest poverty, which misfortune they also ascribed to the curse resting on the house of Eli. Ushaya, the younger, and Chananya, who had returned to Judæa, obtained a precarious living as shoemakers. By reason of the scarcity of customers, they were sometimes obliged to sell their work to prostitutes. Nevertheless, their minds remained so pure and chaste that they were never reproached with a single immodest glance; they were consequently held in high esteem, and were known as the "saints of the land of Israel." These two brothers applied themselves to the Agada, the favorite study in Judæa, while Rabba, their sober brother, who as a child had shown signs of great acuteness of mind, evinced a predilection for the Halacha, in which province his labor was epoch-making. He had determined to remain in Babylonia, and his brothers, unable to quiet their apprehensions concerning his lot, used all their endeavors to persuade him to come to Judæa. "It is not all one," ran their message to him, "whether one dies in or out of Judæa; for the Patriarch Jacob attached great weight to being buried in the Holy Land. Although thou art learned, still it is better to have a master than to educate thyself. And if thou thinkest that there is no teacher of importance to be found in the academies of Judæa, we inform thee that thou wouldst indeed find such a one here." In consequence of this pressing invitation, and contrary to the principles of Judah, his teacher, Rabba emigrated to Judæa. Some time after, however, he returned to Babylonia, probably because he was dissatisfied with the Judæan method of teaching. Rabba's worldly affairs are described as most miserable, and are frequently contrasted with Chasda's uninterrupted happiness.
After the death of his teacher Judah in 299, the Pumbedithan College, which was composed of lovers of dialectics, esteemed Rabba to be the only person worthy of occupying the vacancy thus created in the school. He was therefore offered the honor of becoming Judah's successor, but his exceeding modesty induced him to decline the post. The vacancy was eventually filled by Huna ben Chiya, whose wealth was so immense that he furnished his audience in the lecture-room with gilded seats. Although the greater number of the disciples frequented Sora, the Pumbedithan Academy nevertheless counted 400 students. Both Rabba and his friend Joseph associated themselves with the local academy, and subordinated themselves to the principal, in order to prevent the school from being deprived of the reputation which it had at last succeeded in gaining. When it came to be known in what manner Huna ben Chiya had acquired his wealth, which had been amassed by the farming of tolls, he was given to understand that the dignity of teacher must not be stained by association with that hateful trade, and that he must give up either one or the other. Having abandoned the calling of farmer of tolls, he was recognized by the college, which followed Rabba's example, as a worthy principal of the academy. Joseph was the only person who refused to acquiesce in the appointment. The not altogether spotless reputation of its principal, however, threatened to become a cause of ruin to the Pumbedithan Academy; care was therefore taken after the death of Huna to make a better choice, in order to enlist the sympathy of the people and to attract a numerous audience. Two men appeared worthy to fill this post, Rabba bar Nachmani and Joseph ben Chiya, the one distinguished for Talmudical dialectics, and the other for Halachic erudition. The choice between the two was so difficult that it was determined to take counsel of Judæa, and the following question was accordingly asked: "Who possesses the superiority, Sinai (man of learning), or the remover of mountains (man of acuteness)?" In Tiberias, where the acute method of teaching, although not hated, was nevertheless held in low esteem, the decision was given in favor of the former. But Joseph entertained scruples against accepting this dignity. His nativity had once been cast by a Chaldean, who had informed him that he would obtain a position of great authority, but would not be able to retain it longer than two years and six months, after which he would die. In spite of the legal prohibition forbidding credence to be given to the wisdom of the Chaldeans, the most noted teachers of the Law were unable to free themselves from its influence; daily example was stronger than the Law. Joseph having refused the post thus offered to him, it was conferred upon Rabba (309), and in him the Pumbedithan Academy found its ideal.
Rabba restored anew to the academy its extinguished fame, and attracted to his discourses a crowd of students, amounting at times to as many as 1200. He did not confine his lectures to the practical part of jurisprudence alone, as Judah had done, but treated of all the subjects contained in the Mishna; he sought to reconcile the various contradictions existing in the Mishna, the Boraitas, and the additions made by the Amoraic authorities (Memra), and generally to introduce clearness into the study of the Halacha. He even turned his attention to the remote subject of the laws of Levitical purity, which he succeeded in making comprehensible; but in this branch of study, which had vanished out of every-day life, he stood quite alone, a fact that he frequently lamented. He was distinguished by a desire to enter deeply into the motives not only of the Pentateuch, but also of the Sopheric and Mishnaic laws, and to draw conclusions from them. The formulæ which he employed as an introduction to these investigations ran as follows: "Wherefore has the Law commanded this?" or "Why are such-and-such things prohibited by the teachers of the Law?" His luminous conception and treatment of his subject invested it with life, while the variety which he succeeded in imparting to a dry theme by means of the occasional introduction of an Agadic sentence made it both interesting and captivating. At times he would entertain the students with interesting anecdotes before beginning his discourse, and as soon as he thought that he had put them in a cheerful temper, he would begin to treat of more serious and weighty subjects. His guiding principle was that the soul must be prepared for the reception of serious thoughts, and that this receptivity was best awakened by cheerfulness. Rabba often put catch questions to his pupils, or expressed paradoxical opinions, in order to test their judgment or sharpen their intellect. Rabba holds the same important position among the Amoraim, as Akiba among the Tanaites. He collected scattered and fragmentary subjects under general heads. For this reason the reverence in which he was held by the teachers of the Law equaled that which was entertained for the founder of Babylonian Jewish life. But in proportion as he was beloved by this circle, he was obnoxious to the populace of Pumbeditha. His fellow-countrymen could not forgive this severe censor for the sharp, reproachful words with which, in his honesty and stern morality, he strove to combat their deceits and artifices. Once, on the occasion of a drought, when Rabba had proclaimed a public fast, and had ordered prayers to be offered up, without succeeding in obtaining rain, he exclaimed reproachfully to the populace: "It is not because we leaders of the people are worse than in the time of my master Judah, that Heaven refuses to gratify our wishes; nor is it because we are less diligent in the study of the Law. But what can be done by the representatives of the people when the entire race is degenerate?"
On account of their needy circumstances Rabba and another Amora, Ada, appear to have become the colleagues (Chacham) of Mar-Ukban, a grandchild of Rab, and at that time Prince of the Captivity, at whose expense they were probably supported. While the principals of the Soranian Academy were wealthy, often supporting the entire expenses of the schools, and maintaining a large number of disciples from their own purse, those of Pumbeditha generally possessed but small means. This circumstance necessitated the establishment of an academical fund at Pumbeditha, to which the communities and the Prince of the Captivity probably contributed.
In Rabba's time the Babylonian Jews were the victims of a transitory persecution, which, although insignificant when compared with those which had occurred in the Roman empire, was nevertheless calculated to arouse the sufferers from their feeling of profound safety. It was during the long reign (310–380) of Shabur II, the new king of the Sassanian dynasty, who had been acknowledged as ruler while yet unborn, that the friendly relation in which the Jews had stood to the Persian court became disturbed, and it is possible that they would have been as cruelly persecuted as the Christians, had it not been that Ifra-Ormuzd, the king's mother, was prepossessed in favor of Judaism and the Jews. The account briefly narrates that a body of troops marched into Pumbeditha, whereupon Rabba and Joseph took to flight. A serious charge had been brought against Rabba, the king or his councillors having been secretly informed that, by means of Rabba's discourses during the Kalla months, his 1200 students had been induced to evade the payment of the poll-tax. A royal bailiff was sent out with orders to seize the person of the principal of the Pumbedithan Academy. Being warned in advance, Rabba fled, and in order to escape detection he wandered about in the surrounding country. His death was caused by fright at the rustling of the wind in the trees, which the fugitive mistook for the tramp of advancing soldiery. Abayi and Raba, his most distinguished disciples, together with the rest of the members of the academy, went in search of his corpse, which they eventually found covered over and hidden by birds. They mourned during seven days for this highly esteemed Amora (330). The charge, which was the occasion of Rabba's death, does not seem to have been further prosecuted. The queen-mother, Ifra, even sent a purse of denars to his successor, leaving it to him to make the best and most pious use of it, whereupon he employed it in ransoming Jewish prisoners.
Rabba's successor and friend, Joseph ben Chiya (born about 270, died about 333), was sickly and sensitive, and possessed a passionate disposition. He was aware of his failings and complained that they prevented him from enjoying life. He seems to have been very wealthy, and to have possessed fields, palm-trees and vineyards, from which latter – as he cultivated them more carefully than was generally the case – he obtained better wine than was commonly produced. Upon being afflicted with blindness, he grieved less for the loss of his sight than on account of his being thereby relieved from performing various religious duties.
Joseph was exceptional among the principals of the Pumbedithan Academy, inasmuch as he attached more weight to the acquisition of a knowledge of the Mishna and the Boraïtas by committing them to memory, than to the drawing of ingenious conclusions. For this reason he was known by the title of "Sinai" and "Possessor of Storehouses." Besides studying the Halacha, he turned his attention to the Targum or Chaldaic translation of the Holy Scriptures. The Torah, and probably also isolated portions of the Prophets, which were used for public reading (Haftara), had long ago been translated into the Aramaic dialects – both the Syriac and the Chaldaic. There existed various Chaldaic translations of the Torah for the use of those who were ignorant of Hebrew: one of these, based probably on the favorite Greek version of Akylas, bore the name of Targum Onkelos; the Syrian translation, employed by such of the Jews of Syria and Mesopotamia as spoke Syriac, was called Peshito (the simple). The greater portion of the Prophets, however, had not been translated, and it was Joseph who first took in hand a Chaldaic translation thereof. Some persons believed that this was a work of piety, as Joseph was prevented by his blindness from reading, and was unwilling to recite the Hebrew text by heart, on account of the prohibition against oral quotation of the written Law. He therefore set about translating the Prophets on his own account, in order to be able to quote any desired passage in Chaldaic. Joseph's translation was incorporated in the Targum, and was accepted as a decisive authority on questions relating to the explanation of doubtful words.
He was exceedingly severe in maintaining discipline in his capacity of principal of the Academy; he flogged one of the students – Nathan bar Assa – for journeying on foot from the Academy to Pumbeditha on the second day of one of the festivals. The few years during which he retained his office were in many ways embittered. He was stricken by a severe illness, through which he lost his memory, and it was consequently often necessary for his pupils to remind him that he himself had formerly taught them the very facts which he was then disputing. Although they endeavored to spare his feelings when drawing his attention to his absurd mistakes, nevertheless, in his irritation, he regarded these corrections as a slight, and complainingly exclaimed: "Be indulgent with an old man whom misfortune has caused to forget all he learnt; and forget not that the fragments of the first tables of the Law were preserved by the side of the unbroken tables."
Joseph's hard lot may be considered as typical of the decay of the method of teaching which depended on the power of memory. It heaps up the treasures of learning and tradition, guarding every atom of its hoard as painfully as a miser, and warns off all influences exerted by the employment of the intellect, as if they might obscure its mirror-like purity; but in an unlucky moment the store that has been laboriously collected suddenly vanishes; memory is extinguished, and there remain no means of recovering the lost treasures.
The Soranian school, the home of culture, also began to decline, through neglecting to further the development of the Law. After Chasda's death, the post of principal was held for twelve years (309–320) by Huna's son, Rabba or Rab Abba; but the studious youths were more strongly attracted by the rising star of the Pumbedithan Academy. For this reason Rabba's modesty is the only circumstance in connection with which any remembrance of him is retained. After the death of Rabba bar Huna, the Soranian Academy was deserted, and it was not frequented until half a century later, when it began to regain its lost renown.
After Joseph's death, the college was embarrassed as to whom it should appoint as his successor. There were four who seemed worthy to occupy this post, being all equally esteemed; they were Abayi, Raba, Zeïra II, and Rabba bar Matana. The college accordingly determined to vote for the one who should give the most striking answer, to which no objection could be offered, to a question that was raised. Abayi was victorious in this intellectual tournament, and was chosen as principal. Abayi, whose surname was Nachmani (born about 280, died 338), was an orphan; his father Kailil had died before, his mother immediately after, his birth. A governess took the place of his mother, while Rabba, the sagacious Amora of Pumbeditha, filled that of his father. In after-life, Abayi spoke with gratitude and emotion of his foster-mother, and gave her name to several healing medicaments. To his uncle Rabba, Abayi owed his knowledge of the Law and his skill in Talmudical dialectics. Like Raba, his contemporary Amora, he aroused great expectations during his early youth, and it used to be said of them, "The bud shows what the melon will be." Abayi appears to have possessed but a moderate fortune. Like the majority of the Babylonian teachers of the Law, however, he had a small field of his own, which he cultivated by the agency of a freeman. His character was mild and yielding, and he retained these qualities in his intercourse with the various classes of society. His maxim was: that man should be sagacious in the fear of God, gentle and conciliatory in his speech, and at peace with his brethren, with his relations, in fact, with all the world, even with the heathen abroad, so that he might be beloved and esteemed, and possess influence over his fellow-men. At this time opinions, words, and deeds, were still one and the same. Abayi's integrity was even acknowledged by such of the Samaritans as dwelt in Babylonia. Having once lost an ass which was found by some Samaritans, it was brought back by them to its owner, though he was not able to mention any special mark by which it could be recognized. "If thou wert not Nachmani," said they to him, "we should not have restored the ass even if it had borne some particular mark." Under Abayi's direction of the Pumbedithan Academy (333–338) the number of students diminished to about two hundred, and therefore in remembrance of the crowd of scholars who had flocked thither during the time of his predecessors, Rab and Huna, he called himself an "orphan of orphans." It was not that less interest and pleasure than formerly were now felt in study, but that Abayi possessed a rival in Raba, who had founded a school of his own in Machuza on the Tigris, whither he had attracted many students. Both of these teachers brought the Pumbedithan method to its greatest perfection. Rivaling one another in talent and ingenuity, they discovered answers to questions which Rabba and Joseph had been unable to solve.
The traditions which had been handed down no longer afforded material for discussion, every point which they presented having already been thoroughly elucidated; new themes were therefore propounded and solved by the help of recognized formulæ. These subtle Talmudical dialectics received the names of their most proficient adepts, and were known as the "Havayot (reflections) d'Abayi ve Raba."
Before his death, Abayi heard of the cruel persecutions to which his coreligionists in Judæa were subjected under Constantius. The fugitives who conveyed this sad news to Babylonia, also brought with them new Halachas, from the circle of which Jochanan was the head, and thus inspired the learned students of Babylonia with new vigor.
Abayi died in the prime of life (338). After his death, the office of principal was conferred upon Raba bar Joseph bar Chama of Machuza (born 299, died 352), without any discussion, as if this was expected as a matter of course. Raba was wealthy, talented and acute, but possessed his weak points, which caused him to be considered inferior to his fellow Amoraim, although he surpassed them in acuteness of intellect. He was well acquainted with his own character, and described himself in the following words: "I have always cherished three wishes, of which, while two have been fulfilled, the gratification of the third has not been vouchsafed to me. I desired Huna's learning and Chasda's wealth, and obtained both; but Rabba bar Huna's unassuming modesty was not allotted to me." Although he was superior to the majority of his fellow-countrymen, his character was tainted, nevertheless, with certain peculiarities of the Machuzans; he was luxurious, proud and overbearing, and although his fellow-countrymen did not enjoy the best of reputations in Babylonia, he flattered them to excess. He was exceedingly desirous of winning and retaining their favor. "When I became judge," he relates, "I was afraid that I should no longer retain the attachment of the Machuzans, but as they recognize my impartiality in giving judgment, all must either hate or all love me." Abayi seems to have reproved this tendency of Raba to sacrifice moral dignity for the acquisition of popular favor. "When a teacher of the Law," said he, "is too greatly beloved by his fellow-citizens, it is not because of his great merit, but on account of his indulgence, which causes him to refrain from calling attention to their vices, and from earnestly reprimanding them."
It has already been mentioned that the inhabitants of Machuza were descended for the most part from proselytes, for which reason the aristocratic Babylonian Jews forbore to contract marriages with them. As the Machuzans thus seemed to be at a loss how to obtain wives, Zeïra II declared in a public discourse that it was allowable for them to marry persons who had been born out of wedlock. This permission, however, implying as it did a sort of degradation of the Machuzans, was so offensive to their pride, that they almost stoned him to death with the fruits with which the booths were decorated (the incident occurring during the celebration of the feast of Tabernacles), just as King Alexander Jannæus had once been attacked in the outer court of the temple. Raba could hardly find words severe enough with which to blame Zeïra's candor: "Who would give utterance to so inconsiderate a decision in a community containing so many descendants of proselytes!" In order to enlist the favor of the populace still more strongly on his side, he demonstrated, in opposition to Zeïra's theory, that proselytes might marry even the daughters of priests, and he succeeded by this flattery in charming the Machuzans so greatly that they overwhelmed him with presents of silken stuffs. In after-times Raba attempted to restrict the equality which he had accorded somewhat too freely to the proselytes, probably on account of its having caused displeasure in various circles; at the same time he remarked that proselytes might ally themselves with bastard families. This decision having caused dissatisfaction, Raba appeased his fellow-countrymen with the following words: "I only meant well towards you, and leave you free to act either way."
Another of Raba's failings was that, although exceedingly wealthy, he was not entirely free from covetousness, which he allowed to become apparent on several occasions. A proselyte of Machuza, Issor by name, had deposited with Raba a sum of 12,000 sus (denars), in order to bequeath it to his son, who was being brought up as a student of the Law. Issor having fallen ill, Raba resolved to keep possession of this money as property to which there was no heir, a proselyte being unable to leave his fortune to a son born before his adoption of Judaism, as the Talmudical law does not recognize such offspring as a son. At all events, the principal of the schools – familiar as he was with all the intricacies of the Law – was determined to nullify Issor's disposal of his fortune in favor of his son. Meanwhile, another person who was equally well acquainted with the Law, suggested to the anxious father that, although he was prevented from making over the money in question to his son by will, he was, nevertheless, at liberty to do so by declaring before witnesses that the money belonged to the latter. Raba was greatly incensed at the man who offered this counsel, and complained as bitterly of this secret advice as if he had thereby been deprived of a lawfully acquired fortune. Raba's conduct also violated an accepted Halacha which treats of a similar case. According to this law, although a man is not obliged to hand over to such of the sons as may have become proselytes, the property committed to his keeping by a heathen, of which the latter had not otherwise disposed, an offense is, nevertheless, committed against the higher laws of morality by withholding it from them.
Another example of Raba's selfish conduct is afforded by the fact that he exacted a higher rent from the tenants of his fields than was customary in Babylonia. At times his behavior towards persons of slender means was marked by a harshness which was in glaring opposition to the doctrines of charity and pity, inculcated equally by the Halachas and the Scriptures.
The conduct of his brother Saurim was even more heartless; he posed as a moral censor, and whenever any of the poorer members of the community appeared to him not to be religious enough he made slaves of them, and compelled them to carry him about in his gilded litter. Even to this conduct Raba offered no objection, but sanctioned his brother's arbitrary proceedings by referring to a long-forgotten law, which countenanced the treatment of the Jews as slaves, in case they no longer lived in accordance with the Law.
During this period the simple manners and the honesty which had obtained among the Jews of Babylonia in former times, fell to a low ebb with many of them, and made room for luxury, vanity, and thirst for power. Many a teacher of the Law was clad in gorgeous garments and was carried about in a gilded litter. They no longer felt themselves one with the people from whom they had risen, but constituted a particular caste, a patrician class, who mutually protected and maintained one another's interests, looking down with pride and contempt on the lower orders of the populace. Raba himself admitted that whenever he was called upon to decide a point of law in which a person of the same class of society as himself was concerned, he was unable to sleep until he succeeded in interpreting the law in his favor. If a member of the school brought his produce to market, he was invested with the privilege of being allowed to sell before any one else, in order that he might obtain higher prices. The cause of a member was always heard first in the court. The teachers of the Law of such communities as paid their taxes in a lump sum, were exempt from all imposts. Raba allowed the associates, in places where they were not known, to declare their rank, in order that they might enjoy the advantages attaching thereto. What a contrast to former times, when the Tanaites hesitated, at the risk of their lives even, to derive any benefit from their knowledge of the Law! Raba went to extreme lengths in according privileges to the doctors of the Law. He permitted the associates to pass themselves off as worshipers of fire in order to escape payment of the charag.
The course of conduct thus pursued by the learned classes gradually awoke a dislike of them among the people. The lower classes spoke of them contemptuously as "those scholars." The mockery expressed by this epithet must have been so bitter that on their side the teachers of the Law branded as heretics (Epicureans) all who made use of the expression. Scholarship thus no longer obtained recognition. "What do we profit by the scholars?" the people asked themselves; "all their knowledge is employed for their own benefit." At the head of this opposition to the Rabbis stood the family of the physician, Benjamin of Machuza, which seems to have been possessed of great importance, as Raba paid great attention to its members. "What advantage do we really derive from the teachers of the Law?" said they jeeringly; "they can neither allow us to eat ravens, nor forbid us to eat pigeons?" – meaning that in spite of all their dialectics they were unable to proceed beyond the circle of established customs. Although Raba declared this utterance of Benjamin Assia to be heretical, it does not appear that he excommunicated him, but rather that he treated him with great consideration; it is probable that the latter belonged to the retinue of the Prince of the Captivity.
Meanwhile the zeal for the study of the Law had greatly increased. Disciples crowded in even greater numbers than formerly to Raba's academy in Machuza, neglecting in their ardor their business pursuits. Raba was obliged to warn them against this excess: "I pray you do not come to my school in the spring and autumn months, lest you should neglect the time of the harvest and of the preparation of wine and oil, and so be troubled throughout the year by the cares of life." Raba's discourses were even more popular than Abayi's by reason of the clearness of his explanations, the exactitude of his distinctions, and the boldness of his treatment of the subject-matter of tradition. Raba showed a decided preference for analyzing the Mishna to the bare study of its dry subject-matter. The former method offered a wide field for the employment of dialectical powers, while the Mishna, taken in its simplest sense, became a mere matter of memory. On this account Raba placed the Amoraïm above the Tanaites; the former explained, or explained better, such points as were doubtful to the latter. He was accustomed to say that a grain of pepper (acuteness) was better than a basketful of melons. In contrast to Zeïra I, who was adverse to that method of teaching which encouraged ingenious reasoning, and valued highly the simplicity of the Mishna, Raba declared that "whoso breaketh stones injureth himself thereby (Eccles. x. 9); thus are they characterized who know merely the Mishna; but he who splitteth wood warmeth himself; such are they who are acquainted with the Talmud." The true Talmud, the attractive collection of nice questions, answers, comparisons and distinctions, the lofty flight of thought, which, starting from a point, passes with the quickness of lightning over the intermediate steps of a chain of reasoning, the dialectic form of the Talmud is the product of this period. The triumvirate, Rabba, Abayi, and Raba, were Talmudists in the real meaning of the word, i. e., dialecticians. In this sense the Talmud was the creation of the Pumbedithan and Machuzan schools. In Judæa there was scarcely a notion of it. By reason of his extensive acquirements, his profound intellect, and perhaps also on account of his wealth, Raba remained the sole authority during his continuance at the head of the academy. Questions were referred to him even from Judæa, when the frequent persecutions under Constantius and Gallus involved the Holy Land in the deepest misery.
