Ezekiel 40:19, 27-28, 44

Then he measured the breadth from the forefront of the lower gate unto the forefront of the inner court without, an hundred cubits eastward and northward.

And there was a gate in the inner court toward the south: and he measured from gate to gate toward the south an hundred cubits. And he brought me to the inner court by the south gate: and he measured the south gate according to these measures

And without the inner gate were the chambers of the singers in the inner court, which was at the side of the north gate; and their prospect was toward the south: one at the side of the east gate having the prospect toward the north.
