Ezekiel 43:14; Ezekiel 43:17

14 From 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.

17 The 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.”
