Leviticus 22:3-5

Darby Translation

³ Say unto them, Every one of all your seed, throughout your generations, that approacheth the holy things, which the children of Israel hallow unto Jehovah, having his uncleanness upon him, that soul shall be cut off from before me: I am Jehovah.

⁴ Whatsoever man of the seed of Aaron is a leper, or hath a flux, he shall not eat of the holy things, until he is clean. And he that toucheth any one that is unclean by a dead person, or a man whose seed of copulation hath passed from him;

⁵ or a man that toucheth any crawling thing whereby he becometh unclean, or a man by whom he may become unclean, whatever may be his uncleanness,
