1 Samuel 31:6-8

New Living Translation

⁶ So Saul, his three sons, his armor bearer, and his troops all died together that same day.

⁷ When the Israelites on the other side of the Jezreel Valley and beyond the Jordan saw that the Israelite army had fled and that Saul and his sons were dead, they abandoned their towns and fled. So the Philistines moved in and occupied their towns.

⁸ The next day, when the Philistines went out to strip the dead, they found the bodies of Saul and his three sons on Mount Gilboa.
