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.

but the fat, the kidneys, and the lobe of the liver from the sin offering he offered up in smoke on the altar, just as the Lord had commanded Moses.

Then Aaron presented the people’s offering. He took the goat for the sin offering of the people, and killed it and offered it for sin, as he did the first.

Then Aaron lifted his hands toward the people and blessed them, and came down [from the altar of burnt offering] after presenting the sin offering, the burnt offering, and the peace offerings.

The Sin of Nadab and Abihu

Now Nadab and Abihu, the sons of Aaron, took their respective [ceremonial] censers, put fire in them, placed incense on it and offered strange (unauthorized, unacceptable) fire before the Lord, [an act] which He had not commanded them to do.

But Moses diligently tried to find the goat [that had been offered] as the sin offering, and discovered that it had been burned up [as waste, not eaten]! So he was angry with Aaron’s surviving sons Eleazar and Ithamar, saying,

“Why did you not eat the sin offering in the holy place? For it is most holy; and God gave it to you to remove the guilt of the congregation, to make atonement for them before the Lord.

Then Aaron said to Moses, “This very day they have [obediently] presented their sin offering and their burnt offering before the Lord, but [such terrible things] as these have happened to me [and to them]; if I [and my sons] had eaten a sin offering today would it have been acceptable and pleasing in the sight of the Lord?”

‘When the days of her purification are completed, whether for a son or for a daughter, she shall bring to the priest at the doorway of the Tent of Meeting a one year old lamb as a burnt offering and a young pigeon or a turtledove as a sin offering;

If she cannot afford a lamb then she shall take two turtledoves or young pigeons, one as a burnt offering, the other as a sin offering; the priest shall make atonement for her, and she will be clean.’”

He shall kill the male lamb in the place where they kill the sin offering and the burnt offering, in the sacred place [the courtyard of the tabernacle]; for the guilt offering, like the sin offering, belongs to the priest; it is most holy.

Next the priest shall offer the sin offering and make atonement for the one to be cleansed from his uncleanness, and afterward kill the burnt offering.

and two turtledoves or two young pigeons, such as he can afford, one shall be a sin offering, the other a burnt offering.

He shall offer what he can afford, one as a sin offering and the other as a burnt offering, together with the grain offering. The priest shall make atonement before the Lord on behalf of the one to be cleansed.

and the priest shall offer them, one as a sin offering and the other as a burnt offering. So the priest shall make atonement for the man before the Lord because of his discharge.

and the priest shall offer one as a sin offering and the other as a burnt offering; and he shall make atonement for her before the Lord for her unclean discharge.’

Aaron [as high priest] shall enter the Holy Place in this way: with [the blood of] a young bull as a sin offering and [the blood of] a ram as a burnt offering.

He shall take from the congregation of the Israelites [at their expense] two male goats as a sin offering and one ram as a burnt offering.

Then Aaron shall present the bull as the sin offering for himself, and make atonement for himself and for his house.

Then Aaron shall bring the goat on which the Lord’s lot fell and offer it as a sin offering.

“Aaron shall present the bull as the sin offering for himself and make atonement for himself and for his household (the other priests), and he shall kill the bull as the sin offering for himself.

“Then he shall kill the goat of the sin offering that is for [the sins of] the people and bring its blood within the veil [into the Most Holy Place] and do with its blood as he did with the blood of the bull, and sprinkle it on the mercy seat and in front of the mercy seat.

So he shall make atonement for the Holy Place (Holy of Holies) because of the uncleanness and transgressions of the Israelites, for all their sins. He shall also do this for the Tent of Meeting which is among them in the midst of their uncleanness (impurities).

There shall be no person in the Tent of Meeting when the high priest goes in to make atonement in the Holy Place [within the veil] until he comes out, so that he may make atonement for himself (his own sins) and for his household and for all the congregation of Israel.
