Ezekiel 40:33

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

Cross-reference

In Ezekiel 40:25, the inner south gate also has windows and the same fifty-by-twenty-five cubit dimensions, reinforcing the uniform gate design.

In Ezekiel 40:36, the inner north gate repeats the exact same measurements and features, completing the pattern of identical inner gates.

In Ezekiel 40:24, the south gate is introduced with pillars and portico 'the same size as the others,' but without the full dimensions given here.
