Ezekiel 40:25-27

25The gate and its porches had windows all around like those windows [in the other gateways]; the length was fifty cubits and the width was twenty-five cubits.

26There were seven steps going up to the gate, and its porches were in front of them; and it had palm tree decorations [carved] on its side pillars, one on each side.

27The inner courtyard had a gate toward the south; and he measured from gate to gate toward the south, a hundred cubits.
