Ezekiel 43:13-17

13“These are the measurements of the altar in long cubits, that cubit being a cubit and a handbreadth: Its gutter is a cubit deep and a cubit wide, with a rim of one span around the edge. And this is the height of the altar: 14From the gutter on the ground up to the lower ledge that goes around the altar it is two cubits high, and the ledge is a cubit wide. From this lower ledge to the upper ledge that goes around the altar it is four cubits high, and that ledge is also a cubit wide. 15Above that, the altar hearth is four cubits high, and four horns project upward from the hearth. 16The altar hearth is square, twelve cubits long and twelve cubits wide. 17The upper ledge also is square, fourteen cubits long and fourteen cubits wide. All around the altar is a gutter of one cubit with a rim of half a cubit. The steps of the altar face east.”
