'Fall by the Sword' in the Bible

Thy men shall fall by the sword, and thy mighty in the war.

Every one that is found shall be thrust through; and every one that is taken shall fall by the sword.

And the Assyrian shall fall by the sword, not of man; and the sword, not of men, shall devour him; and he shall flee from the sword, and his young men shall become subject to taskwork.

Behold, I will put a spirit in him, and he shall hear tidings, and shall return unto his own land; and I will cause him to fall by the sword in his own land.
