Leviticus 16:17-19

Living Bible

¹⁷ Not another soul shall be inside the Tabernacle when Aaron enters to make atonement in the Holy Place—not until after he comes out again and has made atonement for himself and his household and for all the people of Israel. ¹⁸ Then he shall go out to the altar before the Lord and make atonement for it. He must smear the blood of the young bull and the goat on the horns of the altar, ¹⁹ and sprinkle blood upon the altar seven times with his finger, thus cleansing it from the sinfulness of Israel and making it holy.^[a]
