1 Samuel 15:32-35 - Samuel Puts Agag To Death
32 Then Samuel said, Bring ye here to me Agag the king of the Amalekites. And Agag came to him cheerfully. And Agag said, Surely the bitterness of death is past.
33 And Samuel said, As thy sword has made women childless, so shall thy mother be childless among women. And Samuel hewed Agag in pieces before LORD in Gilgal.
34 Then Samuel went to Ramah, and Saul went up to his house to Gibeah of Saul. 35 And Samuel came no more to see Saul until the day of his death, for Samuel mourned for Saul, and LORD regretted that he had made Saul king over Israel.
