1 Samuel 31:4-7

But his weapon bearer wouldn’t do it. He was terrified. So Saul took the sword himself and fell on it. When the weapon bearer saw that Saul was dead, he too fell on his sword and died with him. So Saul, his three sons, and his weapon bearer—the men closest to him—died together that day. When the Israelites in the valley opposite and those on the other side of the Jordan saw that their army was in full retreat and that Saul and his sons were dead, they left their cities and ran for their lives. The Philistines moved in and occupied the sites.
