Ezekiel 40:19, 27-28, 44

Then he measured the distance from the inner front of the lower gate to the outer front of the inner court, a hundred cubits on the east side and on the north side.

And there was a gate on the south of the inner court. And he measured from gate to gate toward the south, a hundred cubits. Then he brought me to the inner court through the south gate, and he measured the south gate. It was of the same size as the others.

On the outside of the inner gateway there were two chambers in the inner court, one at the side of the north gate facing south, the other at the side of the south gate facing north.
