TSK · Leviticus 9:2

"This is the thing that you shall do to them to make them holy, to minister to me in the priest's office: take one young bull and two rams without blemish,

"'If his offering is from the flock, from the sheep, or from the goats, for a burnt offering, he shall offer a male without blemish.

He brought the bull of the sin offering, and Aaron and his sons laid their hands on the head of the bull of the sin offering.

Moses said to Aaron, "Draw near to the altar, and offer your sin offering, and your burnt offering, and make atonement for yourself, and for the people; and offer the offering of the people, and make atonement for them; as Yahweh commanded."

He shall take from the congregation of the children of Israel two male goats for a sin offering, and one ram for a burnt offering.

Because of this, he must offer sacrifices for sins for the people, as well as for himself.

by which will we have been sanctified through the offering of the body of Jesus Christ once for all.
