Ezekiel 41:13-15

13And he measured the house: the length a hundred cubits; and the separate place, and the building, and its walls, the length a hundred cubits;

14and the breadth of the front of the house, and of the separate places toward the east, a hundred cubits.

15And he measured the length of the building before the separate place, which was at the back of it, with its galleries on the one side and on the other side, a hundred cubits; and the inner temple, and the porches of the court.
