Ezra 7:9

7And there went up some of the children of Israel, and of the priests, and the Levites, and the singers, and the porters, and the Nethinims, unto Jerusalem, in the seventh year of Artaxerxes the king.

8And he came to Jerusalem in the fifth month, which was in the seventh year of the king.

9For upon the first day of the first month began he to go up from Babylon, and on the first day of the fifth month came he to Jerusalem, according to the good hand of his God upon him.

10For Ezra had prepared his heart to seek the law of the LORD, and to do it, and to teach in Israel statutes and judgments.

11Now this is the copy of the letter that the king Artaxerxes gave unto Ezra the priest, the scribe, even a scribe of the words of the commandments of the LORD, and of his statutes to Israel.
