Ezekiel 43:25-27

“Every day for seven days a male goat, a young bull, and a ram from the flock will be sacrificed as a sin offering. None of these animals may have physical defects of any kind. Do this each day for seven days to cleanse and make atonement for the altar, thus setting it apart for holy use. On the eighth day, and on each day afterward, the priests will sacrifice on the altar the burnt offerings and peace offerings of the people. Then I will accept you. I, the Sovereign LORD, have spoken!”
