Ezekiel 43:25-26, 27

“‘For seven days, prepare a goat for a sin offering daily, and also a bull and a ram from the flock, animals without blemish. For seven days the priests are to get the altar ready for its work, purifying it. This is how you dedicate it.

“‘After these seven days of dedication, from the eighth day on, the priests will present your burnt offerings and your peace offerings. And I’ll accept you with pleasure, with delight! Decree of GOD, the Master.’”
