Anyone from the offspring of Aaron, the priest, who has a blemish, shall not approach to offer sacrifices to the Lord, nor the bread to his God.
Then what will remain of the sacrifice shall be for Aaron and his sons, the Holy of holies from the oblations of the Lord.
Say to Aaron: A man from your offspring, throughout their families, who has a blemish, shall not offer the bread to his God.
They shall be holy to their God, and they shall not pollute his name. For they offer the incense of the Lord and the bread of their God, and because of this they shall be holy.
and they offer the bread of the presence. Therefore, let them be holy, for I also am holy: the Lord, who sanctifies them.
