New King James Version (NKJV)
1 Samuel 15
28 So Samuel said to him, "The Lord has torn the kingdom of Israel from you today, and has given it to a neighbor of yours, who is better than you.
29 And also the Strength of Israel will not lie nor relent. For He is not a man, that He should relent."
30 Then he said, "I have sinned; yet honor me now, please, before the elders of my people and before Israel, and return with me, that I may worship the Lord your God."
31 So Samuel turned back after Saul, and Saul worshiped the Lord.
32 Then Samuel said, "Bring Agag king of the Amalekites here to me." So Agag came to him cautiously. 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 hacked Agag in pieces before the Lord in Gilgal.
34 Then Samuel went to Ramah, and Saul went up to his house at Gibeah of Saul.
35 And Samuel went no more to see Saul until the day of his death. Nevertheless Samuel mourned for 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 mourn for Saul, seeing I have rejected him from reigning over Israel? Fill your horn with oil, and go; I am sending you to Jesse the Bethlehemite. For I have provided Myself a king among his sons."
2 And Samuel said, "How can I go? If Saul hears 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 Then invite Jesse to the sacrifice, and I will show you what you shall do; you shall anoint for Me the one I name to you."
