Leviticus 21 New Revised Standard Version Catholic Edition (NRSVCE)
The Holiness of Priests
21 The Lord said to Moses: Speak to the priests, the sons of Aaron, and say to them:
No one shall defile himself for a dead person among his relatives, 2 except for his nearest kin: his mother, his father, his son, his daughter, his brother; 3 likewise, for a virgin sister, close to him because she has had no husband, he may defile himself for her. 4 But he shall not defile himself as a husband among his people and so profane himself. 5 They shall not make bald spots upon their heads, or shave off the edges of their beards, or make any gashes in their flesh. 6 They shall be holy to their God, and not profane the name of their God; for they offer the Lord’s offerings by fire, the food of their God; therefore they shall be holy. 7 They shall not marry a prostitute or a woman who has been defiled; neither shall they marry a woman divorced from her husband. For they are holy to their God, 8 and you shall treat them as holy, since they offer the food of your God; they shall be holy to you, for I the Lord, I who sanctify you, am holy. 9 When the daughter of a priest profanes herself through prostitution, she profanes her father; she shall be burned to death.
10 The priest who is exalted above his fellows, on whose head the anointing oil has been poured and who has been consecrated to wear the vestments, shall not dishevel his hair, nor tear his vestments. 11 He shall not go where there is a dead body; he shall not defile himself even for his father or mother. 12 He shall not go outside the sanctuary and thus profane the sanctuary of his God; for the consecration of the anointing oil of his God is upon him: I am the Lord. 13 He shall marry only a woman who is a virgin. 14 A widow, or a divorced woman, or a woman who has been defiled, a prostitute, these he shall not marry. He shall marry a virgin of his own kin, 15 that he may not profane his offspring among his kin; for I am the Lord; I sanctify him.
16 The Lord spoke to Moses, saying: 17 Speak to Aaron and say: No one of your offspring throughout their generations who has a blemish may approach to offer the food of his God. 18 For no one who has a blemish shall draw near, one who is blind or lame, or one who has a mutilated face or a limb too long, 19 or one who has a broken foot or a broken hand, 20 or a hunchback, or a dwarf, or a man with a blemish in his eyes or an itching disease or scabs or crushed testicles. 21 No descendant of Aaron the priest who has a blemish shall come near to offer the Lord’s offerings by fire; since he has a blemish, he shall not come near to offer the food of his God. 22 He may eat the food of his God, of the most holy as well as of the holy. 23 But he shall not come near the curtain or approach the altar, because he has a blemish, that he may not profane my sanctuaries; for I am the Lord; I sanctify them. 24 Thus Moses spoke to Aaron and to his sons and to all the people of Israel.

Rules for Priests
21 The Lord said to Moses, “Speak to the priests, the sons of Aaron, and say to them: ‘A priest must not make himself ceremonially unclean for any of his people who die, 2 except for a close relative, such as his mother or father, his son or daughter, his brother, 3 or an unmarried sister who is dependent on him since she has no husband—for her he may make himself unclean. 4 He must not make himself unclean for people related to him by marriage,[a] and so defile himself.
5 “‘Priests must not shave their heads or shave off the edges of their beards or cut their bodies. 6 They must be holy to their God and must not profane the name of their God. Because they present the food offerings to the Lord, the food of their God, they are to be holy.
7 “‘They must not marry women defiled by prostitution or divorced from their husbands, because priests are holy to their God. 8 Regard them as holy, because they offer up the food of your God. Consider them holy, because I the Lord am holy—I who make you holy.
9 “‘If a priest’s daughter defiles herself by becoming a prostitute, she disgraces her father; she must be burned in the fire.
10 “‘The high priest, the one among his brothers who has had the anointing oil poured on his head and who has been ordained to wear the priestly garments, must not let his hair become unkempt[b] or tear his clothes. 11 He must not enter a place where there is a dead body. He must not make himself unclean, even for his father or mother, 12 nor leave the sanctuary of his God or desecrate it, because he has been dedicated by the anointing oil of his God. I am the Lord.
13 “‘The woman he marries must be a virgin. 14 He must not marry a widow, a divorced woman, or a woman defiled by prostitution, but only a virgin from his own people, 15 so that he will not defile his offspring among his people. I am the Lord, who makes him holy.’”
16 The Lord said to Moses, 17 “Say to Aaron: ‘For the generations to come none of your descendants who has a defect may come near to offer the food of his God. 18 No man who has any defect may come near: no man who is blind or lame, disfigured or deformed; 19 no man with a crippled foot or hand, 20 or who is a hunchback or a dwarf, or who has any eye defect, or who has festering or running sores or damaged testicles. 21 No descendant of Aaron the priest who has any defect is to come near to present the food offerings to the Lord. He has a defect; he must not come near to offer the food of his God. 22 He may eat the most holy food of his God, as well as the holy food; 23 yet because of his defect, he must not go near the curtain or approach the altar, and so desecrate my sanctuary. I am the Lord, who makes them holy.’”
24 So Moses told this to Aaron and his sons and to all the Israelites.
