1 Chronicles 10:4-6

New International Version - UK

⁴ Saul said to his armour-bearer, ‘Draw your sword and run me through, or these uncircumcised fellows will come and abuse me.’

But his armour-bearer was terrified and would not do it; so Saul took his own sword and fell on it. ⁵ When the armour-bearer saw that Saul was dead, he too fell on his sword and died. ⁶ So Saul and his three sons died, and all his house died together.
