17 There shall be no man in the tabernacle of meeting when he goes in to make atonement in the Holy Place, until he comes out, that he may make atonement for himself, for his household, and for all the assembly of Israel. 18 And he shall go out to the altar that is before the Lord, and make atonement for it, and shall take some of the blood of the bull and some of the blood of the goat, and put it on the horns of the altar all around.
