18 He said to me: Son of man, thus says the Lord God: These are the ordinances of the altar in the day when they shall make it to offer burnt offerings on it and to sprinkle blood on it.
19 You shall give to the priests the Levites that are of the seed of Zadok who approach Me to minister to Me, says the Lord God, a young bull as a sin offering.
20 You shall take of its blood and put it on its four horns, and on the four corners of the ledge and on the rim all around. Thus you shall cleanse and purge it.
21 You shall take the bull also of the sin offering, and it shall be burned in the appointed place of the temple, outside the sanctuary.
22 On the second day you shall offer a male goat without blemish as a sin offering. And they shall cleanse the altar as they cleansed it with the bull.
23 When you have made an end of cleansing it, you shall offer a young bull without blemish and a ram out of the flock without blemish.
24 You shall offer them before the Lord, and the priests shall cast salt on them, and they shall offer them up as a burnt offering to the Lord.
