Ezekiel 43:20-24

And you shall take some of its blood and put it on its four horns and on the four corners of the ledge, and on the border all around; so you shall cleanse it and make atonement for it.

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

‘And on the second day you shall offer a male goat without blemish as a sin offering, and they shall cleanse the altar from sin as they cleansed it with the bull.

When you have finished cleansing it, you shall offer a bull without blemish and a ram without blemish from the flock.

You shall offer them before the Lord, and the priests shall throw salt on them, and they shall offer them up as a burnt offering to the Lord.
