'Edge of the Sword' in the Bible

David said to all the servants with him in Jerusalem, “Get up. We have to flee, or we will not escape from Absalom! Leave quickly, or he will soon overtake us, heap disaster on us, and strike the city with the edge of the sword.”

They will fall by the edge of the sword and be led captive into all the nations, and Jerusalem will be trampled by the Gentiles until the times of the Gentiles are fulfilled.

quenched the raging of fire, escaped the edge of the sword, gained strength after being weak, became mighty in battle, and put foreign armies to flight.
