Ezekiel 43:19-21

19You are to give a young bull as a sin offering to the Levitical priests of the family of Zadok, who come near to minister before me, declares the Sovereign Lord.

20You are to take some of its blood and put it on the four horns of the altar and on the four corners of the upper ledge and all around the rim, and so purify the altar and make atonement for it.

21You are to take the bull for the sin offering and burn it in the designated part of the temple area outside the sanctuary.
