Ezekiel 43:13-27

13And these are the measures of the altar after the cubits: The cubit is a cubit and an hand breadth; even the bottom shall be a cubit, and the breadth a cubit, and the border of it by its edge on every side shall be a span: and this shall be the higher place of the altar.12 14And from the bottom upon the ground even to the lower ledge shall be two cubits, and the breadth one cubit; and from the smaller ledge even to the greater ledge shall be four cubits, and the breadth one cubit. 15So the altar shall be four cubits; and from the altar and upward shall be four horns.34 16And the altar shall be twelve cubits long, twelve broad, square in its four sides. 17And the ledge shall be fourteen cubits long and fourteen broad in its four sides; and the border about it shall be half a cubit; and the bottom of it shall be a cubit about; and its stairs shall look toward the east. 18And he said to me, Son of man, thus saith the Lord GOD; These are the ordinances of the altar in the day when they shall make it, to offer burnt offerings on it, and to sprinkle blood on it. 19And thou shalt give to the priests the Levites that are of the seed of Zadok, who approach to me, to minister to me, saith the Lord GOD, a young bull for a sin offering. 20And thou shalt take of his blood, and put it on its four horns, and on the four corners of the ledge, and upon the border on every side: thus shalt thou cleanse and purge it. 21Thou shalt take the bull also of the sin offering, and he shall burn it in the appointed place of the house, outside of the sanctuary. 22And on the second day thou shalt offer a kid of the goats without blemish for a sin offering; and they shall cleanse the altar, as they cleansed it with the bull. 23When thou hast finished cleansing it, thou shalt offer a young bull without blemish, and a ram out of the flock without blemish. 24And thou shalt offer them before the LORD, and the priests shall cast salt upon them, and they shall offer them for a burnt offering to the LORD. 25Seven days shalt thou prepare every day a goat for a sin offering: they shall also prepare a young bull, and a ram out of the flock, without blemish. 26Seven days shall they purge the altar and purify it; and they shall consecrate themselves.5 27And when these days are fulfilled, it shall be, that upon the eighth day, and so onward, the priests shall make your burnt offerings upon the altar, and your peace offerings; and I will accept you, saith the Lord GOD.6
