1 Samuel 31:3-6

3The fighting grew fierce around Saul, and when the archers overtook him, they wounded him critically. 4Saul said to his armor-bearer, “Draw your sword and run me through, or these uncircumcised fellows will come and run me through and abuse me.” But his armor-bearer was terrified and would not do it; so Saul took his own sword and fell on it. 5When the armor-bearer saw that Saul was dead, he too fell on his sword and died with him. 6So Saul and his three sons and his armor-bearer and all his men died together that same day.
