Ezekiel 43:13 AMP

[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 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 base of the altar.
