Ezekiel 43:14-16

14 From the gutter on the ground up to the lower ledge it is two cubits high and a cubit wide, and from the smaller ledge up to the larger ledge it is four cubits high and a cubit wide.

15 The altar hearth is four cubits high, and four horns project upward from the hearth.

16 The altar hearth is square, twelve cubits long and twelve cubits wide.
