Leviticus 22:2-8

²“Tell Aaron and his sons to separate themselves from the holy things of the children of Israel, which they make holy to me, and that they not profane my holy name. I am the LORD.

³“Tell them, ‘If anyone of all your offspring throughout your generations approaches the holy things which the children of Israel make holy to the LORD, having his uncleanness on him, that soul shall be cut off from before me. I am the LORD.

⁴“‘Whoever of the offspring of Aaron is a leper or has a discharge shall not eat of the holy things until he is clean. Whoever touches anything that is unclean by the dead, or a man who has a seminal emission,

⁵or whoever touches any creeping thing by which he may be made unclean, or a man from whom he may become unclean, whatever uncleanness he has—

⁶the person that touches any such shall be unclean until the evening, and shall not eat of the holy things unless he bathes his body in water.

⁷When the sun is down, he shall be clean; and afterward he shall eat of the holy things, because it is his bread.

⁸He shall not eat that which dies of itself or is torn by animals, defiling himself by it. I am the LORD.
