Ezekiel 43:24-28

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.

For seven days you shall prepare a goat as a sin offering daily; also a bull and a ram from the flock, both without blemish, shall be prepared.

For seven days they shall make atonement for the altar and purify it; so shall they consecrate it.

When they have completed the days, it shall be that on the eighth day and onward, the priests shall offer your burnt offerings on the altar, and your peace offerings; and I will accept you,’ declares the Lord God.”
