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 of it.
17. And the settle shall be fourteen cubits long and fourteen broad in its four squares; 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 towards the east.
18. And 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 upon it, and to sprinkle blood upon it.
19. And 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 bullock for a sin-offering.
20. And thou shalt take of his blood, and put it on the four horns of it, and on the four corners of the settle, and upon the border around: 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 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.
24. And 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.
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 purge the altar and purify it; and they shall consecrate themselves.
27. And when these days have expired, it shall be, that upon the eighth day, and so forward, the priests shall make your burnt-offerings upon the altar, and your peace-offerings: and I will accept you, saith the Lord GOD.
