Ezekiel 40:14-16

Young's Literal Translation

¹⁴ And he maketh the posts of sixty cubits, even unto the post of the court, the gate all round about;

¹⁵ and by the front of the gate of the entrance, by the front of the porch of the inner gate, fifty cubits;

¹⁶ and narrow windows [are] unto the little chambers, and unto their posts at the inside of the gate all round about -- and so to the arches -- and windows all round about [are] at the inside, and at the post [are] palm-trees.
