C. F. Keil and Franz Delitzsch on Leviticus 7:3-7

Lev 7:3-7

The fat portions only were to be burned upon the altar, viz., the same as in the sin and peace-offerings (see Lev 4:8 and Lev 3:9); but the flesh was to be eaten by the priests, as in the sin-offering (Lev 6:22), inasmuch as there was the same law in this respect for both the sin-offering and trespass-offering; and these parts of the sacrificial service must therefore have had the same meaning, every trespass being a sin (see Lev 6:26). - Certain analogous instructions respecting the burnt-offering and meat-offering are appended in Lev 7:8-10 by way of supplement, as they ought properly to have been given in ch. 6, in the laws relating to the sacrifices in question.
