Leviticus 22:1-9

¹Then the Lord spoke to Moses, saying, ²“Tell Aaron and his sons to be careful with the holy gifts of the sons of Israel, which they dedicate to Me, so as not to profane My holy name; I am the Lord. ³Say to them, ‘If any man among all your descendants throughout your generations approaches the holy gifts which the sons of Israel dedicate to the Lord, while he has an uncleanness, that person shall be cut off from before Me; I am the Lord. ⁴No man of the descendants of Aaron, who is a leper or who has a discharge, may eat of the holy gifts until he is clean. And if one touches anything made unclean by a corpse or if a man has a seminal emission, ⁵or if a man touches any teeming things by which he is made unclean, or any man by whom he is made unclean, whatever his uncleanness; ⁶a person who touches any such shall be unclean until evening, and shall not eat of the holy gifts unless he has bathed his body in water. ⁷But when the sun sets, he will be clean, and afterward he shall eat of the holy gifts, for it is his food. ⁸He shall not eat an animal which dies or is torn by beasts, becoming unclean by it; I am the Lord. ⁹They shall therefore keep My charge, so that they will not bear sin because of it and die thereby because they profane it; I am the Lord who sanctifies them.
