Ezekiel 40:5-8

5And behold, there was a wall on the outside of the house round about, and in the man's hand a measuring-reed of six cubits, [each] of one cubit and a hand breadth. And he measured the breadth of the building, one reed; and the height, one reed.

6And he came to the gate which looked toward the east, and went up its steps; and he measured the threshold of the gate, one reed broad; and the other threshold one reed broad.

7And [each] chamber was one reed long and one reed broad; and between the chambers were five cubits; and the threshold of the gate, beside the porch of the gate within, was one reed.

8And he measured the porch of the gate within, one reed.
