1 Samuel 31:4-5

Then said Saul to his armour-bearer, Draw thy 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 much afraid. So Saul took the sword and fell on it. And when his armour-bearer saw that Saul was dead, he fell likewise on his sword, and died with him.
