Ezekiel 43:16-18

Young's Literal Translation

¹⁶ And the altar [is] twelve long by twelve broad, square in its four squares.

¹⁷ And the border [is] fourteen long by fourteen broad, at its four squares, and the border round about it [is] half a cubit, and the centre to it [is] a cubit round about, and its steps are looking eastward.'

¹⁸ And He saith unto me, `Son of man, Thus said the Lord Jehovah: These [are] statutes of the altar in the day of its being made to cause burnt-offering to go up on it, and to sprinkle on it blood.
