Thus saith the LORD God of Israel; Behold, I will turn back the weapons of war that are in your hands, wherewith ye fight against the king of Babylon, and against the Chaldeans, which besiege you without the walls, and I will assemble them into the midst of this city. I will turn back the weapons - Every attempt you make to repel the Chaldeans shall be unsuccessful.
I will assemble them into the midst of this city - I will deliver the city into their hands.
