Ezekiel 40:20-23

20And the gate of the outer court, that looked toward the north, he measured its length and its breadth.

21And its chambers were three on this side and three on that side; and its posts and its projections were according to the measure of the first gate: its length was fifty cubits, and breadth five and twenty cubits.

22And its windows, and its projections, and its palm-trees were according to the measure of the gate that looked toward the east; and they went up to it by seven steps; and the projections thereof were before them.

23And the gate of the inner court was opposite to the gate toward the north, and toward the east; and he measured from gate to gate a hundred cubits.
