13 And these are the measures of the altar by cubits (the cubit is a cubit and a handbreadth): the bottom shall be a cubit, and the breadth a cubit, and the border thereof by the edge thereof round about a span; and this shall be the base of the altar. 14 And from the bottom upon the ground to the lower ledge shall be two cubits, and the breadth one cubit; and from the lesser ledge to the greater ledge shall be four cubits, and the breadth a cubit. 15 And the upper altar shall be four cubits; and from the altar hearth and upward there shall be four horns. 16 And the altar hearth shall be twelve [cubits] long by twelve broad, square in the four sides thereof. 17 And 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.
18 And 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. 19 Thou 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. 20 And 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. 21 Thou shalt also take the bullock of the sin-offering, and it shall be burnt in the appointed place of the house, without the sanctuary. 22 And 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. 23 When 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. 24 And 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. 25 Seven 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. 26 Seven days shall they make atonement for the altar and purify it; so shall they consecrate it. 27 And when they have accomplished the days, it shall be that upon the eighth day, and forward, the priests shall make your burnt-offerings upon the altar, and your peace-offerings; and I will accept you, saith the Lord Jehovah.
