1 Samuel 15:10-16 English Standard Version (ESV)

10 The word of the Lord came to Samuel: 11 “I regret[a] that I have made Saul king, for he has turned back from following me and has not performed my commandments.” And Samuel was angry, and he cried to the Lord all night. 12 And Samuel rose early to meet Saul in the morning. And it was told Samuel, “Saul came to Carmel, and behold, he set up a monument for himself and turned and passed on and went down to Gilgal.” 13 And Samuel came to Saul, and Saul said to him, “Blessed be you to the Lord. I have performed the commandment of the Lord.” 14 And Samuel said, “What then is this bleating of the sheep in my ears and the lowing of the oxen that I hear?” 15 Saul said, “They have brought them from the Amalekites, for the people spared the best of the sheep and of the oxen to sacrifice to the Lord your God, and the rest we have devoted to destruction.” 16 Then Samuel said to Saul, “Stop! I will tell you what the Lord said to me this night.” And he said to him, “Speak.”

1 Samuel 15:22-31

22 And Samuel said,

“Has the Lord as great delight in burnt offerings and sacrifices,
    as in obeying the voice of the Lord?
Behold, to obey is better than sacrifice,
    and to listen than the fat of rams.
23 For rebellion is as the sin of divination,
    and presumption is as iniquity and idolatry.
Because you have rejected the word of the Lord,
    he has also rejected you from being king.”

24 Saul said to Samuel, “I have sinned, for I have transgressed the commandment of the Lordand your words, because I feared the people and obeyed their voice. 25 Now therefore, please pardon my sin and return with me that I may bow before the Lord.” 26 And Samuel said to Saul, “I will not return with you. For you have rejected the word of the Lord, and the Lord has rejected you from being king over Israel.” 27 As Samuel turned to go away, Saul seized the skirt of his robe, and it tore. 28 And Samuel said to him, “The Lord has torn the kingdom of Israel from you this day and has given it to a neighbor of yours, who is better than you. 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.

1 Samuel 15:34-35

34 Then Samuel went to Ramah, and Saul went up to his house in Gibeah of Saul. 35 And Samuel did not see Saul again until the day of his death, but Samuel grieved over Saul. And the Lord regretted that he had made Saul king over Israel.
