Ezekiel 40:9-13

9And he measured the porch of the gate, eight cubits; and the posts thereof, two cubits; and the porch of the gate was inward.

10And the chambers of the gate which was toward the east were three on this side and three on that side: they three were of one measure; and the posts on this side and on that side had one measure.

11And he measured the breadth of the entry of the gate, ten cubits; [and] the length of the gate, thirteen cubits.

12And there was a border before the chambers of one cubit, and a border of one cubit on the other side; and the chambers were six cubits on this side, and six cubits on that side.

13And he measured the gate from the roof of [one] chamber to the roof [of the other], a breadth of five and twenty cubits, entry opposite entry.
