1 Chronicles 10:7 KJV

5And when his armourbearer saw that Saul was dead, he fell likewise on the sword, and died.

6So Saul died, and his three sons, and all his house died together.

7And when all the men of Israel that were in the valley saw that they fled, and that Saul and his sons were dead, then they forsook their cities, and fled: and the Philistines came and dwelt in them.

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

9And when they had stripped him, they took his head, and his armour, and sent into the land of the Philistines round about, to carry tidings unto their idols, and to the people.
