1 Samuel 15:32-33

Then Samuel said, “Bring me Agag, the king of the Amalekites.” And Agag came to him cheerfully. And Agag said, “Surely the bitterness of death is past.” But Samuel said, “As your sword has made women childless, so shall your mother be childless among women.” And Samuel hewed Agag to pieces before the LORD at Gilgal.
