Leviticus 21:20

“Say to Aaron, ‘None of your offspring throughout their generations who has a defect may approach to offer the bread of his God.

For whatever man he is that has a defect, he shall not draw near: a blind man, or a lame, or he who has a flat nose, or any deformity,

or a man who has an injured foot, or an injured hand,

No man of the offspring of Aaron the priest who has a defect shall come near to offer the offerings of the LORD made by fire. Since he has a defect, he shall not come near to offer the bread of his God.

He shall eat the bread of his God, both of the most holy, and of the holy.

He shall not come near to the veil, nor come near to the altar, because he has a defect; that he may not profane my sanctuaries, for I am the LORD who sanctifies them.’”
