Ezra 7:21-24

21I, King Artaxerxes, give this command to all my officers in the region on the west side of the Euphrates river: You must give Ezra anything that he asks for. He is a priest who studies the law of the God of heaven.

22This is how much you may give to him: 3,400 kilograms of silver, 22,000 litres of grain, 2,200 litres of wine, 2,200 litres of oil, and all the salt that he wants.

23Be careful to give Ezra everything that the God of heaven wants for his temple. I do not want the God of heaven to be angry with the kingdom that I and my sons rule.

24You must not take any kinds of taxes from the men who serve this God in his house. You have no authority to do this. Take no taxes from the priests, the Levites, or the singers, guards, and servants who work in the temple.
