The Lord said to Moses: "Speak to Aaron's sons, the priests, and tell them: A priest is not to make himself ceremonially unclean for a [dead] person among his relatives,a2
except for his immediate family: his mother, father, son, daughter, or brother.
He may make himself unclean for his young unmarried sister in his immediate family.
He is not to make himself unclean for those related to him by marriageb and so defile himself.
"Priests may not make bald spots on their heads, shave the edge of their beards, or make gashes on their bodies.c6
They are to be holy to their God and not profane the name of their God,d because they present the fire offerings to the Lord, the food of their God. They must be holy.
They are not to marry a woman defiled by prostitutionef or divorced by her husband, for the priest is holy to his God.
You are to consider him holy since he presents the food of your God. He will be holy to you because I, the Lord who sets you apart, am holy.
If a priest's daughter defiles herself by promiscuity,g she defiles her father; she must be burned up.h10
"The priest who is highest among his brothers, who has had the anointing oil poured on his head and has been ordainedi to wear the garments, must not dishevel his hairj or tear his garments.k11
He must not go near any dead person or make himself unclean [even] for his father or mother.l12
He must not leave the sanctuary or he will desecrate the sanctuary of his God, for the consecration of the anointing oil of his God is on him;m I am the Lord.
"He is to marry a woman who is a virgin.
He is not to marry a widow, a divorced woman, or one defiled by prostitution. He is to marry a virgin from his own people,
so that he does not corrupt his bloodlinen among his people, for I am the Lord who sets him apart."o
