Ezekiel 40:20-23

20And as for the gate of the outer courtyard which faced the north he measured [both] its length and its width.

21Its guardrooms, three 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 was twenty-five cubits.

22Its windows and its porches and its palm tree decorations had the same measurements as the gate that faced toward the east. It was reached by going up 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.
