 Chapters 6–7 go over much the same ground, but from the point of view of the priest, who, as the one actually carrying out the sacrifice and dividing the "portions", needs to know how to do this.Sacrifices are between God, the priest, and the offerers, although in some cases the entire sacrifice is a single portion to God—i.e., burnt to ashes.Chapters 8–10 describe how Moses consecrates Aaron and his sons as the first priests, the first sacrifices, and God's destruction of two of Aaron's sons for ritual offenses.
