Leviticus 21:6

2except for his relatives that are near to him: for his mother, for his father, for his son, for his daughter, for his brother,

3and for his virgin sister who is near to him, who has had no husband; for her he may defile himself.

4He shall not defile himself, being a chief man among his people, to profane himself.

5“‘They shall not shave their heads or shave off the corners of their beards or make any cuttings in their flesh.

6They shall be holy to their God, and not profane the name of their God, for they offer the offerings of the LORD made by fire, the bread of their God. Therefore they shall be holy.

7“‘They shall not marry a woman who is a prostitute, or profane. A priest shall not marry a woman divorced from her husband; for he is holy to his God.

8Therefore you shall sanctify him, for he offers the bread of your God. He shall be holy to you, for I the LORD, who sanctify you, am holy.

9“‘The daughter of any priest, if she profanes herself by playing the prostitute, she profanes her father. She shall be burned with fire.

10“‘He who is the high priest among his brothers, upon whose head the anointing oil is poured, and who is consecrated to put on the garments, shall not let the hair of his head hang loose, or tear his clothes.
