Leviticus 22:2-4

21st Century King James Version

³ Say unto them: ‘Whosoever he be of all your seed among your generations, who goeth unto the holy things which the children of Israel hallow unto the Lord, having his uncleanness upon him, that soul shall be cut off from My presence: I am the Lord.

⁴ Whatsoever man of the seed of Aaron is a leper or hath a running issue, he shall not eat of the holy things until he is clean. And whoso toucheth any thing that is unclean by the dead, or a man whose seed goeth from him,
