Leviticus 22:1-3 New King James Version (NKJV)

1. Then the Lord spoke to Moses, saying,

2. “Speak to Aaron and his sons, that they separate themselves from the holy things of the children of Israel, and that they do not profane My holy name by what they dedicate to Me: I am the Lord.

3. Say to them: ‘Whoever of all your descendants throughout your generations, who goes near the holy things which the children of Israel dedicate to the Lord, while he has uncleanness upon him, that person shall be cut off from My presence: I am the Lord.
