'Fall by the Sword' in the Bible

And why has Jehovah brought us into this land to fall by the sword, so that our wives and our sons should be a prey? Would it not be better for us to return to Egypt?

For the Amalekites and the Canaanites are there before you, and you shall fall by the sword. Because you have turned away from Jehovah, therefore Jehovah will not be with you.
