Numbers 18:8

And the Lord spake unto Aaron,.... Having pointed out to him the duty of his office, he now informs him of the perquisites of it; or having told him what was his work, now what his wages, or what was his service, and now his maintenance:

behold, I also have given thee the charge of my heave offerings, of all the hallowed things of the children of Israel; such as the heave shoulder and wave breast, and firstfruits, and all other holy things in general, such as were the most holy things; as in Numbers 18:9; and the lighter holy things, as the Jews call them, Numbers 18:11; the charge of these was given to keep for themselves, and for their families:

unto thee have I given them by reason of the anointing: because of his office as a priest, to which he was consecrated by anointing:

and to thy sons by an ordinance for ever; see Leviticus 7:34.
