1 Samuel 31:4-5

Saul said to his armour-bearer, ‘Draw your sword and run me through, or these uncircumcised fellows will come and run me through and abuse me.’ But the armour-bearer was terrified and would not do it; so Saul took his own sword and fell on it. When the armour-bearer saw that Saul was dead, he too fell on his sword and died with him.
