1 Samuel 31:4-5

Then 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 would not do it because he was terrified. Then Saul took his sword and fell on it.  When his armor-bearer saw that Saul was dead, he also fell on his own sword and died with him.
