1 Samuel 31:4-6 MSG

4 Saul said to his weapon bearer, "Draw your sword and put me out of my misery, lest these pagan pigs come and make a game out of killing me."
5 When the weapon bearer saw that Saul was dead, he too fell on his sword and died with him.
6 So Saul, his three sons, and his weapon bearer - the men closest to him - died together that day.
