Leviticus 21:13-17

¹³He shall take for a wife a virgin of his own tribe.

¹⁴But a widow, or one that is put away, or profaned, or a harlot, these he shall not take; but he shall take for a wife a virgin of his own people.

¹⁵And he shall not profane his seed among his people: I am the Lord that sanctifies him.

¹⁶And the Lord spoke to Moses, saying,

¹⁷Say to Aaron, A man of your tribe throughout your generations, who shall have a blemish on him, shall not draw near to offer the gifts of his God.
