Numbers 18:25

Appropriation of the Tithe. - Num 18:26. When the Levites took (received) from the people the tithe assigned them by Jehovah, they were to lift off from it a heave-offering for Jehovah, a tithe of the tithe for Aaron the priest (i.e., for the priesthood; see at Num 18:20). "Your heave-offering shall be reckoned to you as the corn of the threshing-floor, and the fulness (see Exo 22:28) of the wine-press," i.e., according to Num 18:30, as the revenue of the threshing-floor and wine-press; that is to say, as corn and wine which they had reaped themselves.

Aaron being now fully established in the priesthood abundantly to his own satisfaction, and to the satisfaction of the people (which was the good that God brought out of the evil opposition made to him), in this chapter God gives him full instructions concerning his office or rather repeats those which he had before given him. He tells him, I. What must be his work and the care and charge committed to him, and what assistance he should have the Levites in that work (Num 18:1-7). II. What should be his and the Levites' wages for this work. 1. The perquisites or fees peculiar to the priests (Num 18:8-19). 2. The settled maintenance of the Levites (Num 18:20-24). III. The portion which must be paid to the priests out of the Levites' maintenance (Num 18:25-32). Thus every one knew what he had to do, and what he had to live upon.

18:25-32 Just as the Levites received a tithe of the Israelites’ goods (18:24), they in turn were required to give . . . a tithe of the tithe to the priests as their own harvest offering (18:27).
