John Gill Commentary Ezekiel 40:20

"And the gate of the outer court whose prospect is toward the north, he measured the length thereof and the breadth thereof." — Ezekiel 40:20 (ASV)

And the gate of the outward court that looked toward the
north
Or the north gate of this building: having finished the dimensions of the eastern gate, those of the north gate are taken: he measured the length thereof, and the breadth thereof ;
as he had the eastern gate, and which were the same; and so of the south gate, (Ezekiel 40:24) , which denotes the uniformity in religion in the latter day, in the way of entrance into the churches, and in doctrine, discipline, worship, and ordinances.
