1 Samuel 31:1-7

Now the Philistines fought against Israel, and the men of Israel fled before them and fell slain on Mount Gilboa. The Philistines overtook Saul and his sons; and they killed Jonathan and Abinadab and Malchi-shua, Saul’s sons. The battle went heavily against Saul, and the archers hit him; and he was severely wounded by the archers. Saul said to his armor bearer, “Draw your sword and pierce me through with it, otherwise these uncircumcised [Philistines] will come and pierce me through and abuse and mock me.” But his armor bearer would not, because he was terrified [of doing such a thing]. So Saul took his sword and fell on it. When his armor bearer saw that Saul was dead, he also fell on his sword and died with him. So Saul, his three sons, his armor bearer, and all his men died together on that day. When the men of Israel who were on the other side of the valley [of Jezreel], and those who were beyond the Jordan, saw that the other men of Israel had fled and that Saul and his sons were dead, they abandoned the cities and fled; then the Philistines came and lived in them.
