1 Samuel 31:3-6

3When the battle intensified against Saul, the archers overtook him and wounded him critically.

4Then Saul said to his armor-bearer, “Draw your sword and run me through with it, or these uncircumcised men will come and run me through and torture me!”

But his armor-bearer was terrified and refused to do it. So Saul took his own sword and fell on it.

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

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