1 Samuel 31:4-5

Saul said to his armor bearer, “Draw your sword and stab me with it! Otherwise these uncircumcised people will come, stab me, and torture me.” But his armor bearer refused to do it, because he was very afraid. So 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.
