Numbers 18:25-32

The Dues to be Received by the Priests from the Levites. These consisted of a tenth of the tithe paid to the Levites by the people.

Numbers 18:29. every heave offering: better, the whole contribution. The tithe of the tithe is to be of the best.

Numbers 18:30. it shall be counted, etc.: the pronoun refers to the nine-tenths of the tithe which the Levites are to have for themselves. As soon as they have paid their sacred dues to the priests, they will be as free to enjoy the rest as the husbandmen are, who have discharged their obligations to them.

Numbers 18:32. ye shall not profane the holy things: the Levites, by possessing the tithes, will have no temptation to take, and so profane, the offerings which are reserved for the priests.
