Ezekiel 43:15–25

15And the upper altar shall be four cubits; and from the altar hearth and upward there shall be four horns. 16And the altar hearth shall be twelve cubits long by twelve broad, square in the four sides thereof. 17And the ledge shall be fourteen cubits long by fourteen broad in the four sides thereof; and the border about it shall be half a cubit; and the bottom thereof shall be a cubit round about; and the steps thereof shall look toward the east.

18And he said unto me, Son of man, thus saith the Lord Jehovah: These are the ordinances of the altar in the day when they shall make it, to offer burnt-offerings thereon, and to sprinkle blood thereon. 19Thou shalt give to the priests the Levites that are of the seed of Zadok, who are near unto me, to minister unto me, saith the Lord Jehovah, a young bullock for a sin-offering. 20And thou shalt take of the blood thereof, and put it on the four horns of it, and on the four corners of the ledge, and upon the border round about: thus shalt thou cleanse it and make atonement for it. 21Thou shalt also take the bullock of the sin-offering, and it shall be burnt in the appointed place of the house, without the sanctuary. 22And on the second day thou shalt offer a he-goat without blemish for a sin-offering; and they shall cleanse the altar, as they did cleanse it with the bullock. 23When thou hast made an end of cleansing it, thou shalt offer a young bullock without blemish, and a ram out of the flock without blemish. 24And thou shalt bring them near before Jehovah, and the priests shall cast salt upon them, and they shall offer them up for a burnt-offering unto Jehovah. 25Seven days shalt thou prepare every day a goat for a sin-offering: they shall also prepare a young bullock, and a ram out of the flock, without blemish.
