1 Samuel 31:6

The battle went hard against Saul, and the archers overtook him; and he was greatly distressed by reason of the archers.

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 abuse me!” But his armor bearer would not, for he was terrified. Therefore Saul took his sword and fell on it.

When his armor bearer saw that Saul was dead, he likewise fell on his sword, and died with him.

When the men of Israel who were on the other side of the valley, and those who were beyond the Jordan, saw that the men of Israel fled and that Saul and his sons were dead, they abandoned the cities and fled; and the Philistines came and lived in them.

On the next day, when the Philistines came to strip the slain, they found Saul and his three sons fallen on Mount Gilboa.

They cut off his head, stripped off his armor, and sent into the land of the Philistines all around, to carry the news to the house of their idols and to the people.
