Ezekiel 40:20

Then 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.

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

Then he measured the width from the forefront of the lower gate to the forefront of the inner court outside, one hundred cubits, both on the east and on the north.

The lodges of it were three on this side and three on that side. Its posts and its arches were the same as the measure of the first gate: its length was fifty cubits, and the width twenty-five cubits.

Its windows, its arches, and its palm trees were the same as the measure of the gate which faces toward the east. They went up to it by seven steps. Its arches were before them.

There was a gate to the inner court facing the other gate, on the north and on the east. He measured one hundred cubits from gate to gate.
