Leviticus [Pertaining to Levites] 21:21-22

²¹No man of the offspring of Aaron Light-bringer the priest who has a defect shall come near to offer the offerings of Adonai made by fire. Since he has a defect, he shall not come near to offer the bread of his God.

²²He shall eat the bread of his God, both of the most holy, and of the holy.
