1 Chronicles 10:4-5

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