1 Samuel 31:1-4

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.
