Ezekiel 43:18 WEB

¹⁶  The altar hearth shall be twelve [cubits] long by twelve broad, square in the four sides of it.

¹⁷  The ledge shall be fourteen [cubits] long by fourteen broad in the four sides of it; and the border about it shall be half a cubit; and the bottom of it shall be a cubit round about; and the steps of it shall look toward the east.

¹⁸  He said to me, Son of man, thus says the Lord Yahweh: 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  You shall give to the priests the Levites who are of the seed of Zadok, who are near to me, to minister to me, says the Lord Yahweh, a young bull for a sin-offering.

²⁰  You shall take of the blood of it, and put it on the four horns of it, and on the four corners of the ledge, and on the border round about: thus shall you cleanse it and make atonement for it.
