1 Samuel 31:5-7

New Century Version

⁵ When the officer saw that Saul was dead, he threw himself on his own sword, and he died with Saul. ⁶ So Saul, his three sons, and the officer who carried his armor died together that day.

⁷ When the Israelites who lived across the Jezreel Valley and those who lived across the Jordan River saw how the Israelite army had run away, and that Saul and his sons were dead, they left their cities and ran away. Then the Philistines came and lived there.
