Leviticus 22:2–7

“Tell Aaron and his sons to treat with respect the sacred offerings^p the Israelites consecrate to me, so they will not profane my holy name.^q I am the Lord.^r

“Say to them: ‘For the generations to come, if any of your descendants is ceremonially unclean and yet comes near the sacred offerings that the Israelites consecrate to the Lord,^s that person must be cut off from my presence.^t I am the Lord.

“ ‘If a descendant of Aaron has a defiling skin disease or a bodily discharge,^u he may not eat the sacred offerings until he is cleansed. He will also be unclean if he touches something defiled by a corpse^v or by anyone who has an emission of semen, or if he touches any crawling thing^w that makes him unclean, or any person^x who makes him unclean, whatever the uncleanness may be. The one who touches any such thing will be unclean^y till evening.^z He must not eat any of the sacred offerings unless he has bathed himself with water.^a When the sun goes down, he will be clean, and after that he may eat the sacred offerings, for they are his food.^b
