Ezekiel 43:25-27

“You must prepare a goat every day for seven days as a sin offering. Also, the priests must prepare a young bull and male sheep from the flock, which have nothing wrong with them. For seven days the priests are to make the altar pure and ready for God’s service. Then they will give the altar to God. After these seven days, on the eighth day, the priests must offer your burnt offerings and your fellowship offerings on the altar. Then I will accept you, says the Lord GOD.”
