Leviticus 21:21-22
21:21 No man from the descendants of Aaron the priest who has a physical flaw may step forward 1 to present the Lord’s gifts; he has a physical flaw, so he must not step forward to present the food of his God.
21:22 He may eat both the most holy and the holy food of his God,
1 tn Or “shall approach” (see HALOT 670 s.v. נגשׁ).
