1 Samuel 15:32-33

32Then Samuel said, “Bring me Agag king of the Amalekites.” Agag came to him in chains. The meaning of the Hebrew for this phrase is uncertain. And he thought, “Surely the bitterness of death is past.”

33But Samuel said, “As your sword has made women childless, so will your mother be childless among women.” And Samuel put Agag to death before the LORD at Gilgal.
