Ezekiel 43:27

When they have accomplished the days, it shall be that on the eighth day, and forward, the priests shall make your burnt offerings on the altar, and your peace offerings; and I will accept you, says the Lord God."

And when these days are expired, it shall be, that upon the eighth day, and so forward, the priests shall make your burnt offerings upon the altar, and your peace offerings; and I will accept you, saith the Lord GOD.
