He shall put some of the blood on the horns of the altar [of incense] which is before the Lord in the Tent of Meeting; and he shall pour out all the rest of the blood at the base of the altar of burnt offering which is at the doorway of the Tent of Meeting.

So they took what Moses had commanded to the front of the Tent of Meeting, and all the congregation approached and stood before the Lord.

Moses said to Aaron, “Approach the altar and present your sin offering and your burnt offering and make atonement for yourself and for the people; and present the offering of the people and make atonement for them, just as the Lord has commanded.”

So Aaron approached the altar and killed the calf as the sin offering, which was designated for himself.

Then Moses said to Aaron, “This is what the Lord said:

‘I will be treated as holy by those who approach Me,
And before all the people I will be honored.’”

So Aaron, therefore, said nothing.

Moses called Mishael and Elzaphan, the sons of Uzziel who was Aaron’s uncle, and said to them, “Come here, carry your relatives away from the front of the sanctuary and take them outside the camp.”

So they came forward and carried them, still in their undertunics, outside the camp, as Moses had said.

Then the Lord spoke to Moses after the death of the two sons of Aaron who had died when they [irreverently] approached the presence of the Lord.

You shall not uncover the nakedness of your father’s sister; she is your father’s blood relative.

You shall not uncover the nakedness of your mother’s sister, for she is your mother’s blood relative.

You shall not uncover the nakedness of a woman and her daughter, nor shall you take her son’s daughter or her daughter’s daughter to uncover their nakedness (have intimate relations with them); they are [her] blood relatives; it is an outrageous offense.

except for his relatives who are nearest to him, his mother, his father, his son, his daughter, and his brother,

also his virgin sister, who is near to him because she has had no husband; for her he may become unclean.

“Say to Aaron, ‘Throughout their generations none of your descendants who has any [physical] defect shall approach [the altar] to present the food of his God.

No man among the descendants of Aaron the priest who has a [physical] defect and is disfigured or deformed is to approach [the altar] to present the offerings of the Lord by fire. He has a defect; he shall not approach [the altar] to present the food of his God.

but he shall not go within the veil or approach the altar [of incense], because he has a defect, so that he will not profane My sanctuaries; for I am the Lord who sanctifies them.’”

either his uncle or his uncle’s son may redeem him, or one of his blood relatives from his family may redeem him; or if he prospers, he may redeem himself.
