1 Samuel 15:29-35

15:29 The Preeminent One of Israel does not go back on his word or change his mind, for he is not a human being who changes his mind.” 15:30 Saul again replied, “I have sinned. But please honor me before the elders of my people and before Israel. Go back with me so I may worship the Lord your God.” 15:31 So Samuel followed Saul back, and Saul worshiped the Lord.

Samuel Puts Agag to Death

15:32 Then Samuel said, “Bring me King Agag of the Amalekites.” So Agag came to him trembling, thinking to himself, “Surely death is bitter!” 15:33 Samuel said, “Just as your sword left women childless, so your mother will be the most bereaved among women!” Then Samuel hacked Agag to pieces there in Gilgal before the Lord.

15:34 Then Samuel went to Ramah, while Saul went up to his home in Gibeah of Saul. 15:35 Until the day he died Samuel did not see Saul again. Samuel did, however, mourn for Saul, but the Lord regretted that he had made Saul king over Israel.
