Jeremiah 7:2 - Joseph Benson’s Commentary on the Old and New Testaments

Stand in the gates of the Lord's house Namely, the east gate of the temple, which led directly to it, where he delivered this discourse, before all the people who entered there. And proclaim there this word Proclaiming signifies both the authority by which he spake, and the divulging of what he spake plainly and boldly. And as it was in so public a place, namely, at the entrance of the court of the people, not of that of the priests, that he uttered this prophecy, so possibly it might be at one of the three feasts, when all the males from all parts of the country were to appear before the Lord in the courts of his house. In that case he would have many collected together to preach to, and that was the most seasonable time to admonish them not to trust in their privileges.
