Ezekiel 40:15

13He 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.

14He made also posts of threescore cubits, even unto the post of the court round about the gate.

15And from the face of the gate of the entrance unto the face of the porch of the inner gate were fifty cubits.

16And there were narrow windows to the little chambers, and to their posts within the gate round about, and likewise to the arches: and windows were round about inward: and upon each post were palm trees.

17Then brought he me into the outward court, and, lo, there were chambers, and a pavement made for the court round about: thirty chambers were upon the pavement.
