'By the Sword' in the Bible

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

May it fall on the head of Joab and on all his father’s house; and may there not fail from the house of Joab one who has a discharge, or who is a leper, or who takes hold of a distaff, or who falls by the sword, or who lacks bread.”
