1 Samuel 31:4-5

Then Saul said to his armour bearer, “Draw your sword, and thrust me through with it, lest these uncircumcised come and thrust me through and abuse me!” But his armour bearer would not, for he was terrified. Therefore Saul took his sword and fell on it. When his armour bearer saw that Saul was dead, he likewise fell on his sword, and died with him.
