Leviticus 22:1-3

New Century Version

22 The Lord said to Moses, ² “Tell Aaron and his sons: ‘The people of Israel will give offerings to me. These offerings are holy, and they are mine, so you must respect them to show that you respect my holy name. I am the Lord.’ ³ Say to them: ‘If any one of your descendants from now on is unclean and comes near the offerings that the Israelites made holy for me, that person must be cut off from appearing before me. I am the Lord.
