John Gill Commentary Ezekiel 46:21

"Then he brought me forth into the outer court, and caused me to pass by the four corners of the court; and, behold, in every corner of the court there was a court." — Ezekiel 46:21 (ASV)

Then he brought me forth into the utter court From the holy chambers of the priests, and from viewing the place where they boiled the sacrifices, and baked the meat offering: and caused me to pass by the four corners of the court ; in each of the four corners of the outward court there was another court; signifying that there will be courts or churches in the several parts of the world in the latter day.
