C. F. Keil and Franz Delitzsch on Jeremiah 7:2

Jer 7:2

The gate of the temple into which the prophet was to go and stand, is doubtless one of the three gates of the inner or upper court, in which he could stand and address the people gathered before him, in the outer court; perhaps the same in which Baruch read Jeremiah’s prophecies to the people, Jer 36:10 (Schmid, Hitz.). The gates through which the people entered to worship are those of the outer court. The form of address: All Judah, ye who enter, etc., warrant us in assuming that Jeremiah delivered this discourse at one of the great annual festivals, when the people were wont to gather to Jerusalem from the length and breadth of the land.
