Ezra 7:6-7

Ezra was a scholar with a thorough knowledge of the Law which the LORD, the God of Israel, had given to Moses. Because Ezra had the blessing of the LORD his God, the emperor gave him everything he asked for. In the seventh year of the reign of Artaxerxes, Ezra set out from Babylonia for Jerusalem with a group of Israelites which included priests, Levites, Temple musicians, Temple guards, and workers.
