For, lo, I will call all the families of the kingdoms of the north, saith the LORD; and they shall come, and they shall set every one his throne at the entering of the gates of Jerusalem, and against all the walls thereof round about, and against all the cities of Judah.
All the families of the kingdoms of the north - the manifold tribes or clans composing the various kingdoms of Babylon: the specification of these aggravates the picture of calamity (Jeremiah 25:9).
Set every one his throne at ... gates - the usual place of administering justice. The couquering princes will set up their tribunal there, (Jeremiah 39:3, "All the princes of the king of Babylon came in and sat in the middle gate, even Nergal-Sharezer," etc.) Or the reference is to the military pavilion (Jeremiah 43:10, "At the entry of Pharaoh's house in Tahpanhes, Nebuchadrezzar will set his throne upon these stones, and he shall spread his royal pavilion over them"). (Maurer.) I prefer the former view.
