The said to Moses, “Give the following instructions to the priests, the descendants of Aaron. “A priest must not make himself ceremonially unclean by touching the dead body of a relative.
The only exceptions are his closest relatives—his mother or father, son or daughter, brother,
or his virgin sister who depends on him because she has no husband.
But a priest must not defile himself and make himself unclean for someone who is related to him only by marriage.
“The priests must not shave their heads or trim their beards or cut their bodies.
They must be set apart as holy to their God and must never bring shame on the name of God. They must be holy, for they are the ones who present the special gifts to the , gifts of food for their God.
“Priests may not marry a woman defiled by prostitution, and they may not marry a woman who is divorced from her husband, for the priests are set apart as holy to their God.
You must treat them as holy because they offer up food to your God. You must consider them holy because I, the , am holy, and I make you holy.
“If a priest’s daughter defiles herself by becoming a prostitute, she also defiles her father’s holiness, and she must be burned to death.
“The high priest has the highest rank of all the priests. The anointing oil has been poured on his head, and he has been ordained to wear the priestly garments. He must never leave his hair uncombed or tear his clothing.

Then the said to Moses,
“Give the following instructions to Aaron: In all future generations, none of your descendants who has any defect will qualify to offer food to his God.
No one who has a defect qualifies, whether he is blind, lame, disfigured, deformed,
or has a broken foot or arm,
or is hunchbacked or dwarfed, or has a defective eye, or skin sores or scabs, or damaged testicles.
No descendant of Aaron who has a defect may approach the altar to present special gifts to the . Since he has a defect, he may not approach the altar to offer food to his God.
However, he may eat from the food offered to God, including the holy offerings and the most holy offerings.
Yet because of his physical defect, he may not enter the room behind the inner curtain or approach the altar, for this would defile my holy places. I am the who makes them holy.”
So Moses gave these instructions to Aaron and his sons and to all the Israelites.
