1 Samuel 15:24-26

And Saul said unto Samuel, I have sinned; for I have transgressed the commandment of Jehovah, and thy words, because I feared the people, and obeyed their voice. Now therefore, I pray thee, pardon my sin, and turn again with me, that I may worship Jehovah. And Samuel said unto Saul, I will not return with thee; for thou hast rejected the word of Jehovah, and Jehovah hath rejected thee from being king over Israel.
