Ezekiel 43:24

You shall also take the bull of the sin offering, and it shall be burned in the appointed place of the house, outside of the sanctuary.

“On the second day you shall offer a male goat without defect for a sin offering; and they shall cleanse the altar, as they cleansed it with the bull.

When you have finished cleansing it, you shall offer a young bull without defect and a ram out of the flock without defect.

“Seven days you shall prepare every day a goat for a sin offering. They shall also prepare a young bull and a ram out of the flock, without defect.

Seven days shall they make atonement for the altar and purify it. So shall they consecrate it.

When they have accomplished the days, it shall be that on the eighth day and onward, the priests shall make your burnt offerings on the altar and your peace offerings. Then I will accept you,’ says the Lord GOD.”
