18. And he said to me, “Son of man, thus says the Lord God: These are the ordinances for the altar: On the day when it is erected for offering burnt offerings upon it and for throwing blood against it,
19. you shall give to the Levitical priests of the family of Zadok, who draw near to me to minister to me, declares the Lord God, a bull from the herd for a sin offering.
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 all around. Thus you shall purify the altar and make atonement for it.
21. You shall also take the bull of the sin offering, and it shall be burned in the appointed place belonging to the temple, outside the sacred area.
22. And on the second day you shall offer a male goat without blemish for a sin offering; and the altar shall be purified, as it was purified with the bull.
