1 Chronicles 10:2-6

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. Saul groaned to his armor bearer, “Take your sword and kill me before these pagan Philistines come to 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. So Saul and his three sons died there together, bringing his dynasty to an end.
