Ezekiel 40:20-23

²⁰And as for the gate of the outer courtyard which faced north, he measured its length and its width. ²¹It 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. ²²Its 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. ²³The 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.
