Leviticus 9:7-9

Douay-Rheims 1899 American Edition

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.

⁸ And forthwith Aaron, approaching to the altar, immolated the calf for his sin:

⁹ And his sons brought him the blood of it: and he dipped his finger therein, and touched the horns of the altar, and poured the rest at the foot thereof.
