1 Samuel 31:6-8

21st Century King James Version

⁶ So Saul died, and his three sons, and his armorbearer, and all his men that same day together.

⁷ And when the men of Israel who were on the other side of the valley, and those who were on the other side of the Jordan, saw that the men of Israel had fled and that Saul and his sons were dead, they forsook the cities and fled; and the Philistines came and dwelt in them.

⁸ And it came to pass on the morrow, when the Philistines came to strip the slain, that they found Saul and his three sons fallen on Mount Gilboa.
