'Besiege' in the Bible

Thus saith Jehovah the God of Israel: Behold, I will turn back the weapons of war that are in your hands, with which ye fight against the king of Babylon, and against the Chaldeans who besiege you, outside the walls, and I will assemble them into the midst of this city.

He that abideth in this city shall die by the sword, and by the famine, and by the pestilence; but he that goeth out, and deserteth to the Chaldeans that besiege you, he shall live, and his life shall be unto him for a prey.
