1 Samuel 31:6

4Then 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.

5When his armor bearer saw that Saul was dead, he likewise fell on his sword, and died with him.

6So Saul died with his three sons, his armor bearer, and all his men that same day together.

7When 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.

8On the next day, when the Philistines came to strip the slain, they found Saul and his three sons fallen on Mount Gilboa.
