1 Samuel 31:4-10

Then Saul said to his armor-bearer, “Draw your sword, and thrust me through with it, lest these uncircumcised come and thrust me through, and mistreat me.” But his armor-bearer would not, for he feared greatly. Therefore Saul took his own sword and fell upon it. And when his armor-bearer saw that Saul was dead, he also fell upon his sword and died with him. Thus Saul died, and his three sons, and his armor-bearer, and all his men, on the same day together. And when the men of Israel who were on the other side of the valley and those beyond the Jordan saw that the men of Israel had fled and that Saul and his sons were dead, they abandoned their cities and fled. And the Philistines came and lived in them. The next day, when the Philistines came to strip the slain, they found Saul and his three sons fallen on Mount Gilboa. So they cut off his head and stripped off his armor and sent messengers throughout the land of the Philistines, to carry the good news to the house of their idols and to the people. They put his armor in the temple of Ashtaroth, and they fastened his body to the wall of Beth-shan.
