1 Chronicles 10:4-5

New International Version

⁴ Saul said to his armor-bearer, “Draw your sword and run me through, or these uncircumcised fellows will come and abuse me.”

But his armor-bearer was terrified and would not do it; so Saul took his own sword and fell on it. ⁵ When the armor-bearer saw that Saul was dead, he too fell on his sword and died.
