Ezra 7:21-24

21"And I, Artaxerxes the king, make a decree to all the treasurers in the province Beyond the River: Whatever Ezra the priest, the scribe of the Law of the God of heaven, requires of you, let it be done with all diligence,

22up to 100 talents of silver, 100 cors of wheat, 100 baths of wine, 100 baths of oil, and salt without prescribing how much.

23Whatever is decreed by the God of heaven, let it be done in full for the house of the God of heaven, lest his wrath be against the realm of the king and his sons.

24We also notify you that it shall not be lawful to impose tribute, custom, or toll on anyone of the priests, the Levites, the singers, the doorkeepers, the temple servants, or other servants of this house of God.
