Ezekiel

And the little chambers thereof, and the posts thereof, and the arches thereof, according to these measures: and there were windows in it and in the arches thereof round about: it was fifty cubits long, and five and twenty cubits broad.

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 without the inner gate were the chambers of the singers in the inner court, which was at the side of the north gate; and their prospect was toward the south: one at the side of the east gate having the prospect toward the north.
