religious leader of the Jews who returned from exile in Babylon, reformer who reconstituted the Jewish community on the basis of the Torah (Law, or the regulations of the first five books of the Old Testament). His work helped make Judaism a religion in which law was central, enabling the Jews to survive as a community when they were dispersed all over the world. Since his efforts did much to give Jewish religion the form that was to characterize it for centuries after, Ezra has with some justice been called the father of Judaism; i.e., the specific form the Jewish religion took after the Babylonian Exile. So important was he in the eyes of his people that later tradition regarded him as no less than a second Moses.

Knowledge of Ezra (Ezra and Nehemiah, books of) is derived from the biblical books of Ezra and Nehemiah, supplemented by the Apocryphal (not included in the Jewish and Protestant canons of the Old Testament) book of I Esdras (Esdras, First Book of) (Latin Vulgate form of the name Ezra), which preserves the Greek text of Ezra and a part of Nehemiah. It is said that Ezra came to Jerusalem in the seventh year of King Artaxerxes (which Artaxerxes is not stated) of the Persian dynasty then ruling the area. Since he is introduced before Nehemiah, who was governor of the province of Judah from 445 to 433 BC and again, after an interval, for a second term of unknown length, it is sometimes supposed that this was the seventh year of Artaxerxes I (458 BC), though serious difficulties are attached to such a view. Many scholars now believe that the biblical account is not chronological and that Ezra arrived in the seventh year of Artaxerxes II (397 BC), after Nehemiah had passed from the scene. Still others, holding that the two men were contemporaries, regard the seventh year as a scribal error and believe that perhaps Ezra arrived during Nehemiah's second term as governor. But the matter must be left open.

When Ezra arrived the situation in Judah was discouraging. Religious laxity was prevalent, the Law was widely disregarded, and public and private morality was at a low level. Moreover, intermarriage with foreigners posed the threat that the community would mingle with the pagan environment and lose its identity.

Ezra was a priest and “a scribe skilled in the law.” He represented the position of stricter Babylonian Jews who had been upset by reports of laxity in Judah and desired to see matters corrected. Ezra set out in the spring at the head of a sizable caravan and arrived four months later. Ezra apparently had official status as a commissioner of the Persian government, and his title, “scribe of the law of the God of heaven,” is best understood as “royal secretary for Jewish religious affairs,” or the like. The Persians were tolerant of native cults but, in order to avert internal strife and to prevent religion from becoming a mask for rebellion, insisted that these be regulated under responsible authority. The delegated authority over the Jews of the satrapy (administrative area) “beyond the river” (Avar-nahara), or west of the Euphrates River, was entrusted to Ezra; for a Jew to disobey the Law he brought was to disobey “the law of the king.”

The order in which Ezra took the various measures attributed to him is uncertain. He probably presented the Law to the people during the Feast of Tabernacles in the autumn, most likely in the year of his arrival. He also took action against mixed marriages and succeeded in persuading the people to divorce their foreign wives voluntarily. His efforts reached their climax when the people engaged in solemn covenant before God to enter into no more mixed marriages, to refrain from work on the sabbath, to levy on themselves an annual tax for the support of the Temple, regularly to present their tithes and offerings, and otherwise to comply with the demands of the Law.

Nothing further is known of Ezra after his reforms. The 1st-century Hellenistic Jewish historian Josephus states in his Antiquities that he died and was buried in Jerusalem. According to another tradition, he returned to Babylonia, where his supposed grave is a holy site.
