'By the Sword' in the Bible

They mourned, and wept, and fasted until evening, for Saul, and for Jonathan his son, and for the people of the LORD, and for the house of Israel; because they were fallen by the sword.

Let it fall on the head of Joab, and on all his father's house. Let there not fail from the house of Joab one who has an issue, or who is a leper, or who leans on a staff, or who falls by the sword, or who lacks bread."
