Leviticus 16:17-19

New Revised Standard Version Catholic Edition

¹⁷ No one shall be in the tent of meeting from the time he enters to make atonement in the sanctuary until he comes out and has made atonement for himself and for his house and for all the assembly of Israel. ¹⁸ Then he shall go out to the altar that is before the Lord and make atonement on its behalf, and shall take some of the blood of the bull and of the blood of the goat, and put it on each of the horns of the altar. ¹⁹ He shall sprinkle some of the blood on it with his finger seven times, and cleanse it and hallow it from the uncleannesses of the people of Israel.
