1 Chronicles 10:3-7

ISV(i) 3 The heaviest fighting was against Saul, and when the archers who were shooting located Saul, he was gravely wounded by them.
4 Saul ordered his armor bearer, “Draw your sword and run me through with it, or these uncircumcised people will come and abuse me.”
But his armor bearer did not want to do it because he was very frightened, so Saul took the sword and fell on it. 5 When his armor bearer saw that Saul was dead, he also fell on his sword and died. 6 Therefore Saul, his three sons, and all his entire household died together. 7 When that part of the army of Israel that was in the valley saw that the rest of the army of Israel had fled and that Saul and his sons were dead, they abandoned their cities and fled, and the Philistines came and occupied them.
