17 It shall not be baked with leaven. I have given it as their portion of my food offerings. It is a thing most holy, like the sin offering and the guilt offering.

Matthew Henry's Commentary on Leviticus 6:17

Commentary on Leviticus 6:14-23

(Read Leviticus 6:14-23)

The law of the burnt-offerings put upon the priests a great deal of care and work; the flesh was wholly burnt, and the priests had nothing but the skin. But most of the meat-offering was their own. It is God's will that his ministers should be provided with what is needful.
