'Gateways' in the Bible

The pavement (that is, the lower pavement) was by the side of the gates, corresponding to the length of the gates.

The 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.

Then the man (angel) brought me to the inner courtyard by the south gate; and he measured the south gate according to those same measurements.
