JER 21:4

4 Thus saith Hashem Elohei Yisroel; Hineni, I will turn back against you the weapons of milchamah [(war)] that are in your hands, wherewith ye fight against Melech Bavel, and against the Kasdim [(Chaldeans)], which besiege you outside the chomah [(wall)], and I will assemble them inside this city.
