Ezra 7:1-10

Now after this, in the reign of Artaxerxes I [son of Ahasuerus (Xerxes)] king of Persia, Ezra the son (descendant) of Seraiah, the son of Azariah, the son of Hilkiah, the son of Shallum, the son of Zadok, the son of Ahitub, the son of Amariah, the son of Azariah, the son of Meraioth, the son of Zerahiah, the son of Uzzi, the son of Bukki, the son of Abishua, the son of Phinehas, the son of Eleazar, the son of Aaron the chief priest— this Ezra went up from Babylon. He was a scribe skilled in the Law (the five books) of Moses, which the LORD God of Israel had given; and the king granted him everything that he asked, for the hand of the LORD his God was on him. Some of the sons of Israel, with some of the priests and Levites, the singers and gatekeepers, and the temple servants also went up [from Babylon] to Jerusalem in the seventh year of King Artaxerxes. Ezra came to Jerusalem in the fifth month of the seventh year of the king. For on the first of the first month he started out from Babylon, and on the first of the fifth month he arrived in Jerusalem, because the good hand of his God was on him. For Ezra had set his heart (resolved) to study and interpret the Law of the LORD, and to practice it and teach His statutes and ordinances in Israel.
