1 Samuel 31:1-7

Now the Philistines attacked Israel, and the men of Israel fled before them. Many were slaughtered on the slopes of Mount Gilboa. The Philistines closed in on Saul and his sons, and they killed three of his sons—Jonathan, Abinadab, and Malkishua. The fighting grew very fierce around Saul, and the Philistine archers caught up with him and wounded him severely. Saul groaned to his armor bearer, “Take your sword and kill me before these pagan Philistines come to run me through and taunt and torture me.” But his armor bearer was afraid and would not do it. So Saul took his own sword and fell on it. When his armor bearer realized that Saul was dead, he fell on his own sword and died beside the king. So Saul, his three sons, his armor bearer, and his troops all died together that same day. When the Israelites on the other side of the Jezreel Valley and beyond the Jordan saw that the Israelite army had fled and that Saul and his sons were dead, they abandoned their towns and fled. So the Philistines moved in and occupied their towns.
