1 Samuel 31:4-6King James Version (KJV)
4 Then said Saul unto his armourbearer, Draw thy sword, and thrust me through therewith; lest these uncircumcised come and thrust me through, and abuse me. But his armourbearer would not; for he was sore afraid. Therefore Saul took a sword, and fell upon it.
5 And when his armourbearer saw that Saul was dead, he fell likewise upon his sword, and died with him.
6 So Saul died, and his three sons, and his armourbearer, and all his men, that same day together.
