1 Chronicles 10:4-10

4Then said Saul to his armour-bearer, Draw thy sword, and thrust me through with it; lest these uncircumcised come and abuse me. But his armour-bearer would not; for he was much afraid. So Saul took the sword and fell on it.

5And when his armour-bearer saw that Saul was dead, he fell likewise on the sword, and died.

6So Saul died, and his three sons, and all his house died together.

7And when all the men of Israel that were in the valley saw that they fled, and that Saul and his sons were dead, they forsook their cities and fled; and the Philistines came and dwelt in them.

8And it came to pass the next day, that the Philistines came to strip the slain, and they found Saul and his sons fallen on mount Gilboa.

9And they stripped him, and took his head, and his armour, and sent [them] into the land of the Philistines round about, to announce the glad tidings to their idols, and to the people.

10And they put his armour in the house of their 1god, and fastened his head in the house of Dagon.
