1 Chronicles 10:1-5
1-5The Philistines went to war against Israel; the Israelites ran for their lives from the Philistines but fell, slaughtered on Mount Gilboa. The Philistines zeroed in on Saul and his sons and killed his sons Jonathan, Abinadab, and Malki-Shua. The battle went hard against Saul—the archers found him and wounded him. Saul said to his armor bearer, "Draw your sword and finish me off before these pagan pigs get to me and make a sport of my body." But his armor bearer, restrained by both reverence and fear, wouldn't do it. So Saul took his own sword and killed himself. The armor bearer, panicked because Saul was dead, then killed himself.
6-7So Saul and his three sons—all four the same day—died. When all the Israelites in the valley saw that the army had fled and that Saul and his sons were dead, they abandoned their cities and ran off; the Philistines came and moved in.
