Leviticus 22:3–9
3 Say to them: ‘Whoever of all your descendants throughout your generations, who goes near the holy things which the children of Israel dedicate to the Lord, dwhile he has 2uncleanness upon him, that person shall be cut off from My presence: I am the Lord.
4 ‘Whatever man of the descendants of Aaron, who is a eleper or has fa discharge, shall not eat the holy offerings guntil he is clean. And hwhoever touches anything made unclean by a corpse, or ia man who has had an emission of semen, 5 or jwhoever touches any creeping thing by which he would be made unclean, or kany person by whom he would become unclean, whatever his uncleanness may be—6 the person who has touched any such thing shall be unclean until evening, and shall not eat the holy offerings unless he lwashes his body with water. 7 And when the sun goes down he shall be clean; and afterward he may eat the holy offerings, because mit is his food. 8 nWhatever dies naturally or is torn by beasts he shall not eat, to defile himself with it: I am the Lord.
9 ‘They shall therefore keep oMy 3ordinance, plest they bear sin for it and die thereby, if they profane it: I the Lord sanctify them.
