Leviticus 9:4

1 And when the eighth day was come, Moses called Aaron and his sons, and the ancients of Israel, and said to Aaron:

2 Take of the herd a calf for sin, and a ram for a holocaust, both without blemish, and offer them before the Lord.

3 And to the children of Israel thou shalt say: Take ye a he goat for sin, and a calf, and a lamb, both of a year old, and without blemish for a holocaust.

4 Also a bullock and a ram for peace offerings. And immolate them before the Lord, offering for the sacrifice of every one of them flour tempered with oil: for to day the Lord will appear to you.

5 They brought therefore all things that Moses had commanded before the door of the tabernacle: where when all the multitude stood,

6 Moses said: This is the word, which the Lord hath commanded. Do it, and his glory will appear to you.

7 And he said to Aaron: Approach to the altar, and offer sacrifice for thy sin. Offer the holocaust, and pray for thyself and for the people: and when thou hast slain the people's victim, pray for them, as the Lord hath commanded.
