Lev 21:1-9 : 1 The LORD said to Moses, 'Speak to the priests, the sons of Aaron, and tell them: A priest shall not defile himself by coming into contact with a dead person among his people.
2 Except for a close relative, his mother, his father, his son, his daughter, or his brother.
3 And also for his virgin sister, who is near to him and has not been married, he may defile himself for her.
4 He must not defile himself as a chief man among his people, thereby profaning himself.
5 They must not shave bald spots on their heads, trim the edges of their beards, or make cuts on their bodies.
6 They must be holy to their God and must not profane the name of their God. They offer the food offerings of the LORD, the bread of their God, and so they must be holy.
7 They must not marry a woman who is a prostitute or has been profaned, nor may they marry a divorced woman, because priests are holy to their God.
8 You shall sanctify him, for he brings the bread of your God. He shall be holy to you because I, the LORD who sanctifies you, am holy.
9 If a priest's daughter defiles herself by becoming a prostitute, she profanes her father and must be burned with fire.
10 The high priest, who has the oil of anointing poured on his head and who has been consecrated to wear the sacred garments, must not let his hair become unkempt or tear his clothes.
11 He must not go near any dead body or make himself unclean, even for his father or his mother.
12 He must not leave the sanctuary or defile the sanctuary of his God, for the consecration of the anointing oil of his God is on him. I am the LORD.
13 He must marry a woman who is a virgin.
14 He must not marry a widow, a divorced woman, a woman who has been defiled, or a prostitute. He may only marry a virgin from among his own people.
15 He must not defile his descendants among his people, because I am the LORD who sanctifies him.
