Ezekiel 40:28, 44, 47

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.

Then he measured the court: It was square—a hundred cubits long and a hundred cubits wide. And the altar was in front of the temple.
