1 Samuel 15:24-26

24Then Saul said to Samuel, ‘It is true, I have done a bad thing. I did not obey the Lord's command. I did not do what you told me to do. I was afraid of the army. I agreed to do what they wanted.

25Please forgive my sin. Return with me so that I can worship the Lord.’

26But Samuel said to Saul, ‘I will not return with you. You refused to obey the Lord's command. So now the Lord has decided that you will no longer be king of Israel.’
