Leviticus 8:13-15

New Revised Standard Version Catholic Edition

¹³ And Moses brought forward Aaron’s sons, and clothed them with tunics, and fastened sashes around them, and tied headdresses on them, as the Lord commanded Moses.

¹⁴ He led forward the bull of sin offering; and Aaron and his sons laid their hands upon the head of the bull of sin offering, ¹⁵ and it was slaughtered. Moses took the blood and with his finger put some on each of the horns of the altar, purifying the altar; then he poured out the blood at the base of the altar. Thus he consecrated it, to make atonement for it.
