Albert Barnes Commentary Ezekiel 40:2

"In the visions of God brought he me into the land of Israel, and set me down upon a very high mountain, whereon was as it were the frame of a city on the south." — Ezekiel 40:2 (ASV)

By which - Better as in the margin .

As the frame of a city - It is not “a city” which is seen, but a building (the temple and its courts) like a city in its construction, surrounded by massive walls.

On the south - southward, that is, on the southern slope, just as the temple actually stood on Mount Moriah. The temple was at the northeast corner of the city—part of the western portion of the city being more to the north, but no part directly north of the temple.
