Ezekiel 40:19-21

Young's Literal Translation

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;
