Ezekiel 43:26-27

Complete Jewish Bible

²⁶ For seven days, they are to make atonement for the altar and cleanse it; in this way they are to consecrate it. ²⁷ When these days are over, then, on the eighth day and afterwards, the cohanim will present your burnt offerings on the altar and your peace offerings; and I will accept you,’ says Adonai Elohim.”
