We have spoken of a gradual modification of Rabbinical views with the changing circumstances of the nation. This probably comes out most clearly in the advice of the Talmud (Baba M. 42), to divide one's money into three parts--to lay out one in the purchase of land, to invest the second in merchandise, and to keep the third in hand as cash. But there was always this comfort, which Rab enumerated among the blessings of the next world, that there was no commerce there (Ber. 17 a). And so far as this world was concerned, the advice was to engage in business, in order with the profit made to assist the sages in their pursuits, just as Sebua, one of the three wealthy men of Jerusalem, had assisted the great Hillel. From what has been said, it will be inferred that the views expressed as to Palestinian, or even Babylonian Jews, did not apply to those who were "dispersed abroad" among the various Gentile nations. To them, as already shown, commerce would be a necessity, and, in fact, the grand staple of their existence. If this may be said of all Jews of the dispersion, it applies specially to that community which was the richest and most influential among them--we mean the Jews of Alexandria.
Few phases, even in the ever-changeful history of the Jewish people, are more strange, more varied in interest, or more pathetic than those connected with the Jews of Alexandria. The immigration of Jews into Egypt commenced even before the Babylonish captivity. Naturally it received great increase from that event, and afterwards from the murder of Gedaliah. But the real exodus commenced under Alexander the Great. That monarch accorded to the Jews in Alexandria the same rights as its Greek inhabitants enjoyed, and so raised them to the rank of the privileged classes. Henceforth their numbers and their influence grew under successive rulers. We find them commanding Egyptian armies, largely influencing Egyptian thought and inquiry, and partially leavening it by the translation of the Holy Scriptures into Greek. Of the so-called Temple of Onias at Leontopolis, which rivalled that of Jerusalem, and of the magnificence of the great synagogue at Alexandria, we cannot speak in this place. There can be no doubt that, in the Providence of God, the location of so many Jews in Alexandria, and the mental influence which they acquired, were designed to have an important bearing on the later spread of the Gospel of Christ among the Greek-speaking and Grecian-thinking educated world. In this, the Greek translation of the Old Testament was also largely helpful. Indeed, humanly speaking, it would have scarcely been possible without it. At the time of Philo the number of Jews in Egypt amounted to no less than one million. In Alexandria they occupied two out of the five quarters of the town, which were called after the first five letters of the alphabet. They lived under rulers of their own, almost in a state of complete independence. Theirs was the quarter Delta, along the seashore. The supervision of navigation, both by sea and river, was wholly entrusted to them. In fact, the large export trade, especially in grain--and Egypt was the granary of the world--was entirely in their hands. The provisioning of Italy and of the world was the business of the Jews. It is a curious circumstance, as illustrating how little the history of the world changes, that during the troubles at Rome the Jewish bankers of Alexandria were able to obtain from their correspondents earlier and more trustworthy political tidings than any one else. This enabled them to declare themselves in turn for Caesar and for Octavius, and to secure the full political and financial results flowing from such policy, just as the great Jewish banking houses at the beginning of this century were similarly able to profit by earlier and more trustworthy news of events than the general public could obtain.
