Ezekiel 40:23 (KJV)

And the little chambers thereof were three on this side and three on that side; and the posts thereof and the arches thereof were after the measure of the first gate: the length thereof was fifty cubits, and the breadth five and twenty cubits.

And their windows, and their arches, and their palm trees, were after the measure of the gate that looketh toward the east; and they went up unto it by seven steps; and the arches thereof were before them.

And the gate of the inner court was over against the gate toward the north, and toward the east; and he measured from gate to gate an hundred cubits.

After that he brought me toward the south, and behold a gate toward the south: and he measured the posts thereof and the arches thereof according to these measures.

And there were windows in it and in the arches thereof round about, like those windows: the length was fifty cubits, and the breadth five and twenty cubits.
