Ezekiel 40:11-15

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

The space also before the little chambers was one cubit on this side, and the space was one cubit on that side: and the little chambers were six cubits on this side, and six cubits on that side.

He measured then the gate from the roof of one little chamber to the roof of another: the breadth was five and twenty cubits, door against door.

He made also posts of threescore cubits, even unto the post of the court round about the gate.

And from the face of the gate of the entrance unto the face of the porch of the inner gate were fifty cubits.
