Leviticus 22:2-3

Speak to Aaron and his sons so that they a abstain from the holy things of the people of Israel, which they b dedicate to me, so that they do not c profane my holy name: I am the  Lord. Say to them, ‘If any one of all your offspring throughout your generations approaches the holy things that the people of Israel dedicate to the  Lord, while d he has an uncleanness, that person shall be cut off from my presence: I am the  Lord.
