Stand in the gate; i.e. not an outer gate (for the outer court would be filled with the people whom Jeremiah was to address), but one of the three gates which led from the inner court to the outer. Probably it was the gate where Baruch recited the prophecies of Jeremiah at a later period, and which is designated "the new gate of the Lord's house," and said to have been situated in the "upper" i.
e. inner court (Jeremiah 36:10; comp. Jeremiah 26:10). We may conjecture that either one of the three great festivals or some extraordinary fast had brought a large number of people together at the temple.
