Ezekiel 43:27 DBY

²⁵  Seven days shalt thou offer daily a goat for a sin-offering; they shall also offer a young bullock, and a ram out of the flock without blemish.

²⁶  Seven days shall they make atonement for the altar and purify it, and consecrate it.

²⁷  And when these days are ended, it shall be that upon the eighth day and onwards the priests shall offer your burnt-offerings upon the altar, and your peace-offerings; and I will accept you, saith the Lord Jehovah.
