Leviticus Chapter 21 Verse 17 - 24
17.) Say to Aaron, If a man of your family, in any generation, is damaged in body, let him not come near to make the offering of the bread of his God.
18.) For any man whose body is damaged may not come near: one who is blind, or has not the use of his legs, or one who has a broken nose or any unnatural growth,
19.) Or a man with broken feet or hands,
20.) Or one whose back is bent, or one who is unnaturally small, or one who has a damaged eye, or whose skin is diseased, or whose sex parts are damaged;
21.) No man of the offspring of Aaron whose body is damaged in any way may come near to give the fire offerings of the Lord: he is damaged, he may not come near to make the offerings.
22.) He may take of the bread of God, the holy and the most holy;
23.) But he may not go inside the veil or come near the altar, because he is damaged; and he may not make my holy places common; for I the Lord have made them holy.
24.) These are the words which Moses said to Aaron and to his sons and to all the children of Israel.
