1 Chronicles 10:5-7

New King James Version

⁵ And when his armorbearer saw that Saul was dead, he also fell on his sword and died. ⁶ So Saul and his three sons died, and all his house died together. ⁷ And when all the men of Israel who were in the valley saw that they had fled and that Saul and his sons were dead, they forsook their cities and fled; then the Philistines came and dwelt in them.
