Leviticus 21:17-23 NLT

17 “Give the following instructions to Aaron: In all future generations, none of your descendants who has any defect will qualify to offer food to his God.
18 No one who has a defect qualifies, whether he is blind, lame, disfigured, deformed,
19 or has a broken foot or arm,
20 or is hunchbacked or dwarfed, or has a defective eye, or skin sores or scabs, or damaged testicles.
21 No descendant of Aaron who has a defect may approach the altar to present special gifts to the . Since he has a defect, he may not approach the altar to offer food to his God.
22 However, he may eat from the food offered to God, including the holy offerings and the most holy offerings.
23 Yet because of his physical defect, he may not enter the room behind the inner curtain or approach the altar, for this would defile my holy places. I am the who makes them holy.”
