Ezekiel 43:20-22

Revised Standard Version Catholic Edition

²⁰ And you shall take some of its blood, and put it on the four horns of the altar, and on the four corners of the ledge, and upon the rim round about; thus you shall cleanse the altar and make atonement for it. ²¹ You shall also take the bull of the sin offering, and it shall be burnt in the appointed place belonging to the temple, outside the sacred area. ²² And on the second day you shall offer a he-goat without blemish for a sin offering; and the altar shall be cleansed, as it was cleansed with the bull.
