'By the Sword' in the Bible

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

Let it fall upon the head of Joab, and upon all his father's house. And 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.
