Ezekiel 43:13-17

13 The Altar
“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:

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.

17 The upper ledge also is square, fourteen cubits long and fourteen cubits wide, with a rim of half a cubit and a gutter of a cubit all around. The steps of the altar face east.”
