Ezekiel 43:25-27

New Revised Standard Version, Anglicised Catholic Edition

²⁵ For seven days you shall provide daily a goat for a sin-offering; also a bull and a ram from the flock, without blemish, shall be provided. 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.
