Leviticus 21:16 MSG

[16] God spoke to Moses: “Tell Aaron, None of your descendants, in any generation to come, who has a defect of any kind may present as an offering the food of his God. That means anyone who is blind or lame, disfigured or deformed, crippled in foot or hand, hunchbacked or dwarfed, who has anything wrong with his eyes, who has running sores or damaged testicles. No descendant of Aaron the priest who has any defect is to offer gifts to God; he has a defect and so must not offer the food of his God. He may eat the food of his God, both the most holy and the holy, but because of his defect he must not go near the curtain or approach the Altar. It would desecrate my Sanctuary. I am God who makes them holy.”
