Leviticus 21:8, 15, 23

You shall consecrate him, therefore, for he offers the food of your God; he shall be holy to you; for I the LORD, who sanctifies you, am holy.

so that he will not profane or dishonor his children among his people; for I am the LORD who sanctifies the high priest.’ ”

but he shall not go within the veil or approach the altar [of incense], because he has a defect, so that he will not profane My sanctuaries; for I am the LORD who sanctifies them.’ ” [Heb 7:28]
