Ezra 7:24

Moreover, in respect to all the priests and the Levites, the musicians, the keepers of the gates, the Nathinims, and those employed in the service of the house of God, this hath been notified to you, Take no toll of them. Thou shalt have no authority to exercise dominion over them.

Also this has been declared to you, with respect to all the priests, and Levites, the singers, porters, Nathinim and ministers of the house of God, let no tribute be paid to thee; thou shalt not have power to oppress them.
