1 Samuel 15:26-29

But Samuel replied, “I will not go back with you! Since you have rejected the LORD’s command, he has rejected you as king of Israel.” As Samuel turned to go, Saul tried to hold him back and tore the hem of his robe. 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. 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!”
