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 settle 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 in 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 that be of the seed of Zadok, which approach unto 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 settle, 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, without 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 did cleanse it with the bullock.
