Ezekiel 40:19, 27-28, 44

Then he measured the distance from the inside of the lower gateway to the outside of the inner court; it was a hundred cubits on the east side as well as on the north.

The inner court also had a gate facing south, and he measured from this gate to the outer gate on the south side; it was a hundred cubits. Then he brought me into the inner court through the south gate, and he measured the south gate; it had the same measurements as the others.

Outside the inner gate, within the inner court, were two rooms, one at the side of the north gate and facing south, and another at the side of the south gate and facing north.
