Leviticus 21:16-24 NKJV
And the LORD spoke to Moses, saying, “Speak to Aaron, saying: ‘No man of your descendants in succeeding generations, who has any defect, may approach to offer the bread of his God. For any man who has a defect shall not approach: a man blind or lame, who has a marred face or any limb too long, a man who has a broken foot or broken hand, or is a hunchback or a dwarf, or a man who has a defect in his eye, or eczema or scab, or is a eunuch. No man of the descendants of Aaron the priest, who has a defect, shall come near to offer the offerings made by fire to the LORD. He has a defect; he shall not come near to offer the bread of his God. He may eat the bread of his God, both the most holy and the holy; only he shall not go near the veil or approach the altar, because he has a defect, lest he profane My sanctuaries; for I the LORD sanctify them.’ ”
And Moses told it to Aaron and his sons, and to all the children of Israel.
