1 Samuel 31:4-6

4Saul groaned to his armor bearer, “Take your sword and kill me before these pagan Philistines come to run me through and taunt and torture me.” But his armor bearer was afraid and would not do it. So Saul took his own sword and fell on it.

5When his armor bearer realized that Saul was dead, he fell on his own sword and died beside the king.

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