Ezekiel 40:28, 44, 47

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.

So he measured the court, an hundred cubits long, and an hundred cubits broad, foursquare; and the altar that was before the house.
