'By the Sword' in the Bible

And till evening they gave themselves to sorrow and weeping, and took no food, weeping for Saul and for Jonathan, his son, and for the people of the Lord and for the men of Israel; because they had come to their end by the sword.

Then David said to the man, Go and say to Joab, Do not let this be a grief to you; for one man may come to his death by the sword like another: put up an even stronger fight against the town, and take it: and do you put heart into him.
