1 Samuel 31:1-7

1 Now the Philistines were fighting against Israel: and the men of Israel went in flight before the Philistines, falling down wounded in Mount Gilboa.
2 And the Philistines overtook Saul and his sons; and they put to death Jonathan and Abinadab and Malchi-shua, the sons of Saul.
3 And the fight was going badly for Saul, and the archers came across him, and he was wounded by the archers.
4 Then Saul said to the servant who had the care of his arms, Take out your sword and put it through me, before these men without circumcision come and make sport of me. But his servant, full of fear, would not do so. Then Saul took out his sword, and falling on it, put an end to himself.
5 And when his servant saw that Saul was dead, he did the same, and was united with him in death.
6 So death overtook Saul and his three sons and his servant on the same day.
7 And when the men of Israel across the valley and on the other side of Jordan saw that the army of Israel was in flight and that Saul and his sons were dead, they came out of their towns and went in flight; and the Philistines came and took them for themselves.
