¹⁰ And there were three side rooms on either side of the east gate; the three were of the same size; and the jambs on either side were of the same size. ¹¹ Then he measured the breadth of the opening of the gateway, ten cubits; and the breadth of the gateway, thirteen cubits. ¹² There was a barrier before the side rooms, one cubit on either side; and the side rooms were six cubits on either side.
