'Die by the Sword' in the Bible

Then Jesus said to him, “Put your sword back in its place; for all those who habitually draw the sword will die by the sword.

And people will die by the sword and be led captive into all nations. And Jerusalem will be trampled on by the [unconverted] Gentiles [i.e., by the Romans and later by others] until the times of [domination by] the Gentiles are fulfilled.
