1 Samuel 31:4-5

Then said Saul to his armorbearer, Draw thy sword, and thrust me through therewith, lest these uncircumcised come and thrust me through, and abuse me. But his armorbearer would not; for he was sore afraid. Therefore Saul took his sword, and fell upon it. And when his armorbearer saw that Saul was dead, he likewise fell upon his sword, and died with him.
