Ancient Jewish History:
Banking & Bankers

There is little likelihood that financial transactions played a prominent role in the pre-Exilic epoch in Ereẓ Israel; according to the ethos of Jewish society, then founded on a pronounced agrarian structure, lending was part of the assistance a man owed to his neighbor or brother in need (cf. Deut. 23:21). During the Babylonian era Jews had greater opportunities to come into contact with a highly developed banking tradition and to participate in credit operations. After the Exile, commerce and credit certainly had a place in Ereẓ Israel. Though the society remained predominantly agrarian, Jerusalem had a number of wealthy families, including tax agents and landowners, who speculated and deposited their gains in the Temple, which had in some ways the function of a national bank (see *Heliodorus ). Organized banking probably arose in connection with Ma'aserot ("tithes"), in particular Ma'aser sheni, and the pilgrimages to Jerusalem, through the activities of the *money changers . The use of Greek terms indicates a strong Hellenistic influence on the establishment of banking. Meanwhile, the Jewish communities forming in the Diaspora, the most important at first being that of *Babylonia, were given an impulse toward a new way of life by the longstanding traditions of a capitalist type of economy existing around them (see Nippur and *Murashu 's sons). In Babylonia, Jews engaged in financial transactions: some were farmers of taxes and customs, and the wealthiest of them were landowners; among the latter were *Huna, the head of the academy of Sura, and Rav *Ashi . However, talmudic references show that the standards of an agrarian economy were still dominant and therefore gamblers and usurers were not thought trustworthy witnesses (see e.g., Sanh. 3:3).

Another important Jewish colony was to be found at *Alexandria, center of the trade between the Mediterranean and the Arabian and Indian world, where Jews were engaged not only in commerce and international trade but in moneylending too. According to *Josephus, a Jewish tax agent was able to make a loan of 3,000 talents. The *alabarch Alexander Lysimachus, who loaned King *Agrippa I 200,000 drachmas (Jos., Ant., 18:159–160), was also the steward of Antonia, mother of Emperor Claudius. Another Alexandrian Jew was treasurer to Candace, queen of Ethiopia.
