Ezra 7:7-17

7 And there went up also to Jerusalem, in the seventh year of Ar-ta-xerx'es the king, some of the people of Israel, and some of the priests and Levites, the singers and gatekeepers, and the temple servants.
8 And he came to Jerusalem in the fifth month, which was in the seventh year of the king;
9 for on the first day of the first month he began to go up from Babylonia, and on the first day of the fifth month he came to Jerusalem, for the good hand of his God was upon him.
10 For Ezra had set his heart to study the law of the LORD, and to do it, and to teach his statutes and ordinances in Israel.
11 This is a copy of the letter which King Ar-ta-xerx'es gave to Ezra the priest, the scribe, learned in matters of the commandments of the LORD and his statutes for Israel:
12 "Ar-ta-xerx'es, king of kings, to Ezra the priest, the scribe of the law of the God of heaven. And now
13 I make a decree that any one of the people of Israel or their priests or Levites in my kingdom, who freely offers to go to Jerusalem, may go with you.
14 For you are sent by the king and his seven counselors to make inquiries about Judah and Jerusalem according to the law of your God, which is in your hand,
15 and also to convey the silver and gold which the king and his counselors have freely offered to the God of Israel, whose dwelling is in Jerusalem,
16 with all the silver and gold which you shall find in the whole province of Babylonia, and with the freewill offerings of the people and the priests, vowed willingly for the house of their God which is in Jerusalem.
17 With this money, then, you shall with all diligence buy bulls, rams, and lambs, with their cereal offerings and their drink offerings, and you shall offer them upon the altar of the house of your God which is in Jerusalem.
