New American Standard Bible (NASB)
1 Samuel 15
29 Also the Glory of Israel will not lie or change His mind; for He is not a man that He should change His mind."
30 Then he said, "I have sinned; but please honor me now before the elders of my people and before Israel, and go back with me, that I may worship the Lord your God."
31 So Samuel went back following Saul, and Saul worshiped the Lord.
32 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."
33 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.
34 Then Samuel went to Ramah, but Saul went up to his house at Gibeah of Saul.
35 Samuel did not see Saul again until the day of his death; for Samuel grieved over Saul. And the Lord regretted that He had made Saul king over Israel.
1 Samuel 16
1 Now the Lord said to Samuel, "How long will you grieve over Saul, since I have rejected him from being king over Israel? Fill your horn with oil and go; I will send you to Jesse the Bethlehemite, for I have selected a king for Myself among his sons."
2 But Samuel said, "How can I go? When Saul hears of it, he will kill me." And the Lord said, "Take a heifer with you and say, ’I have come to sacrifice to the Lord.’
3 You shall invite Jesse to the sacrifice, and I will show you what you shall do; and you shall anoint for Me the one whom I designate to you."
4 So Samuel did what the Lord said, and came to Bethlehem. And the elders of the city came trembling to meet him and said, "Do you come in peace?"
