1 Samuel 15:26-29

And Samuel said unto Saul, I will not return with thee: for thou hast rejected the word of the LORD, and the LORD hath rejected thee from being king over Israel. And as Samuel turned about to go away, he laid hold upon the skirt of his mantle, and it rent. And Samuel said unto him, The LORD hath rent the kingdom of Israel from thee this day, and hath given it to a neighbour of thine, that is better than thou. And also the Strength of Israel will not lie nor repent: for he is not a man, that he should repent.
