Ezekiel 43:18-20

New Catholic Bible

¹⁸ Then he said to me: Son of man, thus says the Lord God: These are the regulations for the altar when it has been erected for the offering of holocausts upon it and for the sprinkling of blood upon it. ¹⁹ You are to present a young bull as a sin offering to the Levitical priests of the family of Zadok who are authorized to draw near me in order to minister to me, says the Lord God.

²⁰ You are to take some of its blood and put it on the four horns of the altar and on the four corners of the ledge and upon the surrounding rim. Thus, you will purify it and make atonement for it.
