The wisdom of Jesus ben Sira (Sirach) is contained in the book commonly called _Ecclesiasticus_ (q.v.). At a time when men were attracted by the wisdom and science of the Greeks, he taught that all wisdom came from Yahweh who had chosen Israel to receive it in trust. He discouraged inquiries into the nature and purpose of things: it was enough for him that Yahweh had created and ruled the universe. If a man had leisure to be wise--and this is not for many--he should study the Scriptures which had come down, and so become a scribe. For the scribe, as for the man at the plough-tail, the Law was the rule of life. All, however much or little preoccupied with worldly business, must fear God, from whom come good things and evil, life, death, poverty and riches. It was not for men to meddle with secrets which are beyond human intelligence. Enough that the individual did his duty in the state of life in which he was set and left behind him a good name at his death. The race survives--"the days of Israel are unnumbered." Every member of the congregation of Israel must labour, as God has appointed, at some handicraft or profession to provide for his home. It is his sacred duty and his private interest to beget children and to train them to take his place. The scholar is apt to pity the smith, the potter, the carpenter and the farmer: with better reason he is apt to condemn the trader who becomes absorbed in greed of gain and so deserts the way of righteousness and fair dealing. As a teacher Jesus gave his own services freely. For the soldier he had no commendation. There were physicians who understood the use of herbs, and must be rewarded when their help was invited. But, whatever means each head of a family adopted to get a livelihood, he must pay the priest's dues. The centre of the life of Israel was the Temple, over which the high priest presided and which was inhabited by Yahweh, the God of Israel. The scribe could train the individual in morals and in manners; but the high priest was the ruler of the nation. As ruler of the nation the high priest paid its tribute to Egypt, its overlord. But Josephus reports of one Onias that for avarice he withheld it. The sequel shows how a Jew might rise to power in the civil service of the Egyptian Empire and yet remain a hero to some of the Jews--provided that he did not intermarry with a Gentile. For Joseph, the son of Tobiah and nephew of Onias, went to court and secured the taxes of Palestine, when they were put up to auction. As tax-farmer he oppressed the non-Jewish cities and so won the admiration of Josephus.
