Concerning the law of peace offerings, the Lord said in part,
“The flesh that touches any unclean thing shall not be eaten. It shall be burned with fire. And as for the clean flesh, all who are clean may eat of it” (Leviticus 7:19).
“the flesh of the sacrifice of the peace offering that belongs to the LORD, that person shall be cut off from his people” (Leviticus 7:21).
If we want to approach the Lord, we have to be holy.
