Charles Ellicott Commentary Leviticus 6:29

"Every male among the priests shall eat thereof: it is most holy." — Leviticus 6:29 (ASV)

All the males among the priests. —Not only did the officiating priest, whose perquisite the flesh of the sin offering became, and his male children, partake of it, but he could invite any other priests and their sons to the meal. It is to this practice that the apostle refers when he says, We have an altar whereof they have no right to eat which serve the tabernacle (Hebrews 13:10).
