Leviticus 16:1-6 Revised Standard Version Catholic Edition (RSVCE)
The Day of Atonement
16 The Lord spoke to Moses, after the death of the two sons of Aaron, when they drew near before the Lord and died; 2 and the Lord said to Moses, “Tell Aaron your brother not to come at all times into the holy place within the veil, before the mercy seat which is upon the ark, lest he die; for I will appear in the cloud upon the mercy seat. 3 But thus shall Aaron come into the holy place: with a young bull for a sin offering and a ram for a burnt offering. 4 He shall put on the holy linen coat, and shall have the linen breeches on his body, be girded with the linen girdle, and wear the linen turban; these are the holy garments. He shall bathe his body in water, and then put them on. 5 And he shall take from the congregation of the people of Israel two male goats for a sin offering, and one ram for a burnt offering.
6 “And Aaron shall offer the bull as a sin offering for himself, and shall make atonement for himself and for his house.
