Ezekiel 43:26-27

New Revised Standard Version, Anglicised Catholic Edition

²⁶ For seven days shall they make atonement for the altar and cleanse it, and so consecrate it. ²⁷ When these days are over, then from the eighth day onwards the priests shall offer upon the altar your burnt-offerings and your offerings of well-being; and I will accept you, says the Lord God.
