I Chronicles 10:1-7

Now the Philistines fought against Israel; and the men of Israel fled from before the Philistines, and fell slain on Mount Gilboa. Then the Philistines followed hard after Saul and his sons. And the Philistines killed Jonathan, Abinadab, and Malchishua, Saul’s sons. The battle became fierce against Saul. The archers hit him, and he was wounded by the archers. Then Saul said to his armorbearer, “Draw your sword, and thrust me through with it, lest these uncircumcised men come and abuse me.” But his armorbearer would not, for he was greatly afraid. Therefore Saul took a sword and fell on it. And when his armorbearer saw that Saul was dead, he also fell on his sword and died. So Saul and his three sons died, and all his house died together. And when all the men of Israel who were in the valley saw that they had fled and that Saul and his sons were dead, they forsook their cities and fled; then the Philistines came and dwelt in them.
