Ezra 7:14-16

14You are sent by the king and his seven advisers to inquire about Judah and Jerusalem with regard to the Law of your God, which is in your hand. 15Moreover, you are to take with you the silver and gold that the king and his advisers have freely given to the God of Israel, whose dwelling is in Jerusalem, 16together with all the silver and gold you may obtain from the province of Babylon, as well as the freewill offerings of the people and priests for the temple of their God in Jerusalem.
