Ezekiel 40:19-23

Then he measured the width from the front of the lower gate to the front of the exterior of the inner courtyard, a hundred cubits on the east and on the north.

And as for the gate of the outer courtyard which faced north, he measured its length and its width.

It had three guardrooms on each side; and its side pillars and its porches had the same measurement as the first gate. Its length was fifty cubits, and the width twenty-five cubits.

Its windows, its porches, and its palm tree decorations had the same measurements as the gate which faced east; and it was reached by seven steps, and its porch was in front of them.

The inner courtyard had a gate opposite the gate on the north as well as the gate on the east; and he measured a hundred cubits from gate to gate.
