No man that has a blemish of the descendants of Aaron the priest shall come near to offer the offerings of the LORD made by fire: he has a blemish; he shall not come near to offer the bread of his God.
Speak unto Aaron, saying, Whosoever he be of your descendants in their generations that has any blemish, let him not approach to offer the bread of his God.
They shall be holy unto their God, and not profane the name of their God: for the offerings of the LORD made by fire, and the bread of their God, they do offer: therefore they shall be holy.
