1 Samuel 15:29-33 English Standard Version (ESV)

29. And also the Glory of Israel will not lie or have regret, for he is not a man, that he should have regret.”

30. Then he said, “I have sinned; yet honor me now before the elders of my people and before Israel, and return with me, that I may bow before the Lord your God.”

31. So Samuel turned back after Saul, and Saul bowed before the Lord.

32. Then Samuel said, “Bring here to me Agag the king of the Amalekites.” And Agag came to him cheerfully. Agag said, “Surely the bitterness of death is past.”

33. And Samuel said, “As your sword has made women childless, so shall your mother be childless among women.” And Samuel hacked Agag to pieces before the Lord in Gilgal.
