Ezekiel 43:19-21

19You shall give to the priests, the Levites who are from the descendants of Zadok, who are close to Me to minister to Me,’ says the Lord God, ‘a young bull for a sin offering [as a memorial to Christ’s sacrifice].

20And you shall take some of its blood and put it on the four horns [of the altar of burnt offering] and on the four corners of the ledge and on the border all around; thus you shall cleanse it (from sin) and make atonement for it.

21You shall also take the bull for the sin offering, and it shall be burned in the appointed place of the temple, outside the sanctuary.
