Vayikra 7:35 Meaning and Commentary

Leviticus 7:35

This [is the portion] of the anointing of Aaron
Of his being anointed to the priestly office; this is the part allotted and assigned him for the execution of it; this is the reward, as Aben Ezra interprets it, of his faithful performance of it, namely, his having the wave breast and heave shoulder of the peace offerings, and a cake out of everyone of the unleavened cakes, together with the leavened bread, besides other perquisites from other offerings: and of the anointing of his sons;
the successors of him in the priest hood; the Targum of Jonathan adds, above all their brethren the Levites: out of the offerings of the Lord made by fire;
out of such whose fat on the several parts of them was burnt with fire, such as the peace offerings were: in the day when he presented them to minister unto the Lord in the
priest's office;
when they were ordered to be taken out from among the children of Israel, and to be consecrated to, and invested with, the priest's office, as they were by Moses, and presented by him unto him as his priests; at that time the above portion was assigned them, as follows.

36 Which Hashem commanded to be given them of the Bnei Yisroel, in the day that He anointed them, by a chukkat olam throughout their dorot.

37 This is the torah of the olah (burnt offering), of the minchah (grain offering), and of the chattat (sin offering), and of the asham (trespass offering), and of the ordination offerings, and of the zevach hashelamim (sacrifice of the peace offerings);
