Matthew Poole and continuators on Jeremiah 20:4

4 For thus saith the LORD, Behold, I will make thee a terrour to thy self, and to all thy friends, and they shall fall by the sword of their enemies, and thine eye shall behold it, and I will give all Judah into the hand of the king of Babylon, and he shall carry them captive into Babylon, and shall slay them with the sword .

God now expoundeth the name of Magor missabib, threatning to fill this wicked Priest with Terrors, that he and all his friends should be affrighted reflecting upon his most miserable state, and condition, and his friends from whom he might possibly expect some relief should be as miserable as he, and it should be an addition to his misery, that his eyes should see it, and see his whole country ruined, some being slain by the sword of the King of Babylon, others by him carried into Captivity.
