Ezekiel 40:16

14He also made posts, sixty cubits; and the court reached to the posts, around the gate.

15From the forefront of the gate at the entrance to the forefront of the inner porch of the gate were fifty cubits.

16There were closed windows to the side rooms, and to their posts within the gate all around, and likewise to the arches. Windows were around inward. Palm trees were on each post.

17Then he brought me into the outer court. Behold, there were rooms and a pavement made for the court all around. Thirty rooms were on the pavement.

18The pavement was by the side of the gates, corresponding to the length of the gates, even the lower pavement.
