Leviticus 21:16-24

16The Lord said to Moses,

17‘Talk to Aaron. Say, “A priest who does not have a perfect body must not sacrifice the burnt offerings to God.” This rule is for now and for all time.

18A priest who cannot see must not sacrifice the food to God. A priest who cannot walk must not sacrifice food to God. A priest with a body that is the wrong shape must not offer food to God.

19A priest with a hand that is the wrong shape must not offer food to God. A priest with a foot that is the wrong shape must not offer food to God.

20A priest with a back that is not straight must not offer food to God. Neither must a priest who is very small offer a food gift. A priest who has an eye disease or a skin disease must not offer food to God. Neither must a priest offer food if his testicles are spoiled.

21If a priest's son has something wrong with his body, he must not come near to the altar. He must not give the food offering to the Lord.

22He can eat God's holy food and God's most holy food.

23But none of Aaron's family who is not perfect can go near the holy curtain or the altar. He would make the holy places unclean. I am the Lord. I make them holy.’

24Moses told all these rules to Aaron, to his sons and to all Israel's people.
