1 Samuel 31:6-8

Holman Christian Standard Bible

⁶ So on that day, Saul died together with his three sons, his armor-bearer, and all his men.

⁷ When the men of Israel on the other side of the valley and on the other side of the Jordan saw that Israel’s men had run away and that Saul and his sons were dead, they abandoned the cities and fled. So the Philistines came and settled in them.

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