Ezekiel 43:16-18 Modern English Version (MEV)
16 The altar hearth shall be twelve cubits long by twelve wide,[a] square in its four corners. 17 The ledge shall be fourteen cubits[b] long and fourteen wide in the four squares. And the border about it shall be half a cubit.[c] And its bottom shall be a cubit all around. And its stairs shall face east.
18 He said to me: Son of man, thus says the Lord God: These are the ordinances of the altar in the day when they shall make it to offer burnt offerings on it and to sprinkle blood on it.
