John Gill Commentary Ezekiel 40:27

"And there was a gate to the inner court toward the south: and he measured from gate to gate toward the south a hundred cubits." — Ezekiel 40:27 (ASV)

And there was a gate in the inner court toward the south

Which answered to the gate of the outward court before mentioned: and he measured from gate to gate toward the south an hundred cubits ;

from the gate of the inward court, to the gate of the outward court southward, were just the same dimensions as in the east and north gates, (Ezekiel 40:19Ezekiel 40:23) .
