1 Chronicles 10:5

3The battle went hard against Saul, and the archers overtook him; and he was distressed by reason of the archers.

4Then Saul said to his armor bearer, “Draw your sword, and thrust me through with it, lest these uncircumcised come 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.

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

7When all the men of Israel who were in the valley saw that they fled, and that Saul and his sons were dead, they abandoned their cities, and fled; and the Philistines came and lived in them.
