Ezekiel 43:13; Ezekiel 43:14

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:

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.
