Ezekiel 40:18

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.

17 And he bringeth me in unto the outer court, and lo, chambers and a pavement made for the court all round about -- thirty chambers on the pavement --

18 and the pavement unto the side of the gates over-against the length of the gates [is] the lower pavement;

19 and he measureth the breadth from before the lower gate, to the front of the inner court, on the outside, a hundred cubits, eastward and northward.

20 As to the gate of the outer court whose front [is] northward, he hath measured its length and its breadth;

21 and its little chambers, three on this side, and three on that side, and its posts and its arches have been according to the measure of the first gate, fifty cubits its length, and the breadth five and twenty by the cubit;
