Ezekiel 43:19–20

19 You are to give a bull from the herdd as a sin offeringe to the Levitical priests who are from the offspring of Zadok,f who approach me in order to serve me.”g This is the declaration of the Lord God. 20 “You are to take some of its blood and apply it to the four hornsh of the altar, the four corners of the ledge, and all around the rim. In this way you will purify the altar and make atonement for it.i
