Ezekiel 43:13

“And these are the measurements of the altar [of burnt offering] in cubits (the cubit being a [long] cubit [the length of a forearm] and a hand width): the ^[e]base shall be a cubit [long] and a cubit wide, with its border on its edge all around it of a span [in width]. And this shall be the height of the ^[f]base of the altar.
