Ezekiel Chapter 40 Vs. 27

 The South Gate

And there was a gate in the inner court toward the south: and he measured from gate to gate toward the south an hundred cubits. Eze 40:27

gate to gate... The gate of the inner court wall facing the south outer court gate was the same as the other gates of the inner wall which faced the gates in the outer wall.

Each of these gates are part of that 150 foot by 150 foot enclosure.

Ezekiel was then led from the east gate of the outer court to the north gate (Eze. 40:20-23) and to the south gate (Eze. 40:24-27). The design and dimensions of both gates were identical to those of the gate facing east.
