Ezekiel

And there were narrow windows to the little chambers, and to their posts within the gate round about, and likewise to the arches: and windows were round about inward: and upon each post were palm trees.

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 chambers and the entries thereof were by the posts of the gates, where they washed the burnt offering.
