Ezra 7:21-24

And I, even I Artaxerxes the king, do make a decree to all the treasurers that are beyond the River, that whatsoever Ezra the priest, the scribe of the law of the God of heaven, shall require of you, it be done with all diligence, unto a hundred talents of silver, and to a hundred measures of wheat, and to a hundred baths of wine, and to a hundred baths of oil, and salt without prescribing how much. Whatsoever is commanded by the God of heaven, let it be done exactly for the house of the God of heaven; for why should there be wrath against the realm of the king and his sons? Also we certify you, that touching any of the priests and Levites, the singers, porters, Nethinim, or servants of this house of God, it shall not be lawful to impose tribute, custom, or toll, upon them.
