Ezekiel 40:6-16

Then he went into the gateway facing east, going up its steps, and measured the threshold of the gate, one reed deep. And the side rooms, one reed long and one reed broad; and the space between the side rooms, five cubits; and the threshold of the gate by the vestibule of the gate at the inner end, one reed. Then he measured the vestibule of the gateway, on the inside, one reed. Then he measured the vestibule of the gateway, eight cubits; and its jambs, two cubits; and the vestibule of the gate was at the inner end. 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. Then he measured the width of the opening of the gateway, ten cubits; and the length of the gateway, thirteen cubits. There was a barrier before the side rooms, one cubit on either side. And the side rooms were six cubits on either side. Then he measured the gate from the ceiling of the one side room to the ceiling of the other, a breadth of twenty-five cubits; the openings faced each other. He measured also the vestibule, sixty cubits. And around the vestibule of the gateway was the court. From the front of the gate at the entrance to the front of the inner vestibule of the gate was fifty cubits. And the gateway had windows all around, narrowing inwards toward the side rooms and toward their jambs, and likewise the vestibule had windows all around inside, and on the jambs were palm trees.
