1 Samuel 15:24–31
24 Then Saul admitted to Samuel, “Yes, I have sinned. I have disobeyed your instructions and the Lord’s command, for I was afraid of the people and did what they demanded. 25 But now, please forgive my sin and come back with me so that I may worship the Lord.”
27 As Samuel turned to go, Saul tried to hold him back and tore the hem of his robe. 28 And Samuel said to him, “The Lord has torn the kingdom of Israel from you today and has given it to someone else—one who is better than you. 29 And he who is the Glory of Israel will not lie, nor will he change his mind, for he is not human that he should change his mind!”
30 Then Saul pleaded again, “I know I have sinned. But please, at least honor me before the elders of my people and before Israel by coming back with me so that I may worship the Lord your God.” 31 So Samuel finally agreed and went back with him, and Saul worshiped the Lord.
