Ezekiel 43:16-18

American Standard Version

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.
