Leviticus 21:8-11 Catholic Public Domain Version (CPDV)

8. and they offer the bread of the presence. Therefore, let them be holy, for I also am holy: the Lord, who sanctifies them.

9. If the daughter of a priest will have been taken into prostitution, and will have violated the name of her father, she shall be consumed by fire.

10. The high priest, that is, the priest who is the greatest among his brothers, upon whose head the oil of anointing has been poured, and whose hands have been consecrated for the priesthood, and who has been vested with the holy vestments: he shall not expose his head; he shall not rend his vestments.

11. And he shall not enter to any dead body whatsoever; likewise, not even by his father or mother shall he be contaminated.
