Ezekiel 43:21-23 Modern English Version (MEV)
21 You shall take the bull also of the sin offering, and it shall be burned in the appointed place of the temple, outside the sanctuary.
22 On the second day you shall offer a male goat without blemish as a sin offering. And they shall cleanse the altar as they cleansed it with the bull. 23 When you have made an end of cleansing it, you shall offer a young bull without blemish and a ram out of the flock without blemish.
