Leviticus 21:1-9

1Then the LORD said to Moses, “Speak to Aaron’s sons, the priests, and tell them that a priest is not to defile himself for a dead person among his people, 2except for his immediate family—his mother, father, son, daughter, or brother, 3or his unmarried sister who is near to him, since she has no husband. 4He is not to defile himself for those related to him by marriage, and so profane himself.

5Priests must not make bald spots on their heads, shave off the edges of their beards, or make cuts in their bodies. 6They must be holy to their God and not profane the name of their God. Because they present to the LORD the food offerings, the food of their God, they must be holy.

7A priest must not marry a woman defiled by prostitution or divorced by her husband, for the priest is holy to his God. 8You are to regard him as holy, since he presents the food of your God. He shall be holy to you, because I the LORD am holy—I who set you apart. 9If a priest’s daughter defiles herself by prostituting herself, she profanes her father; she must be burned in the fire.
