Ezekiel 43:25, 27

For seven days you shall prepare daily a goat for a sin offering; also a young bull and a ram from the flock, without blemish, shall be prepared.

When they have completed these days, on the eighth day and from then onward, the priests shall offer your burnt offerings on the altar, and your peace offerings; and I will accept you,’ says the Lord GOD.” [Rom 12:1; 1 Pet 2:5]
