1 Samuel 15:32-33

Then said Samuel, Bring ye hither to me Agag the king of the Amalekites. And Agag came unto him cheerfully. And Agag said, Surely the bitterness of death is past. And Samuel said, As thy sword hath made women childless, so shall thy mother be childless among women. And Samuel hewed Agag in pieces before Jehovah in Gilgal.
