1 Samuel 15:11, 23, 26, 28

It repenteth me that I have set up Saul to be king; for he is turned back from following me, and hath not performed my commandments. And Samuel was wroth; and he cried unto Jehovah all night.

For rebellion is as the sin of witchcraft, and stubbornness is as idolatry and teraphim. Because thou hast rejected the word of Jehovah, he hath also rejected thee from being king.

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.

And Samuel said unto him, Jehovah hath rent the kingdom of Israel from thee this day, and hath given it to a neighbor of thine, that is better than thou.
