'By the Sword' in the Bible

And they lamented aloud, and wept, and fasted until the evening, - for Saul, and for Jonathan his son, and for the people of Yahweh, and for the house of Israel, because they had fallen by the sword.

Let it be hurled upon the head of Joab, and against all his father's house, - and let there not fail from the house of Joab - one that hath an issue, or a leper, or one that leaneth on a crutch, or that falleth by the sword, or that lacketh bread.
