Jeremiah 21:4

Jer 21:4 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.

Ver. 4. Behold, I will turn back the weapons of war, ] i.e., I will render them vain and useless; as it is God who in battle ordereth the ammunition, Jer 50:25 and maketh the weapons vain or prosperous. Isa 54:17 Jer 50:9 This was plainly seen at Edgehill fight.
