Ezekiel 43:21

18 Then He said to me: “Son of man, this is what the Lord GOD says: ‘These are the statutes for the altar on the day it is constructed, so that burnt offerings may be sacrificed on it and blood may be sprinkled on it:

19 You are to give a young bull from the herd as a sin offering to the Levitical priests who are of the family of Zadok, who approach Me to minister before Me, declares the Lord GOD.

20 You are to take some of its blood and put it on the four horns of the altar, on the four corners of the ledge, and all around the rim; thus you will cleanse the altar and make atonement for it.

21 Then you are to take away the bull for the sin offering and burn it in the appointed part of the temple area outside the sanctuary.

22 On the second day you are to present an unblemished male goat as a sin offering, and the altar is to be cleansed as it was with the bull.

23 When you have finished the purification, you are to present a young, unblemished bull and an unblemished ram from the flock.

24 You must present them before the LORD; the priests are to sprinkle salt on them and sacrifice them as a burnt offering to the LORD.
