Ezekiel 43:13-23

13 "And these are the mesurements of the altar in cubits (the cubit is a cubit and a handbreadth): even the bottom shall be a cubit and the breadth a cubit, and the border thereof by the edge thereof round about shall be a span; and this shall be the higher place of the altar.
14 And from the bottom upon the ground even to the lower ledge shall be two cubits and the breadth one cubit; and from the lesser ledge even to the greater ledge shall be four cubits and the breadth one cubit.
15 So the altar shall be four cubits; and from the altar and upward shall be four horns.
16 And the altar shall be twelve cubits long, twelve broad, square in the four squares thereof.
17 And the ledge shall be fourteen cubits long and fourteen broad in the four squares thereof; and the border about it shall be half a cubit, and the bottom thereof shall be a cubit about; and his stairs shall look toward the east."
18 And He said unto me, "Son of man, thus saith the Lord GOD: These are the ordinances of the altar on the day when they shall make it, to offer burnt offerings thereon and to sprinkle blood thereon.
19 And thou shalt give to the priests, the Levites who are of the seed of Zadok, who approach Me to minister unto Me, saith the Lord GOD, 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 and purge it.
21 Thou shalt take the bullock also of the sin offering, and he shall burn it in the appointed place of the house, outside the sanctuary.
22 And 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 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.
