1 Samuel 15:22-24

And Samuel said, Hath the LORD as great delight in burnt offerings and sacrifices, As in obeying the voice of the LORD? Behold, to obey is better than sacrifice, And to hearken than the fat of rams. For rebellion is as the sin of witchcraft, And stubbornness is as iniquity and idolatry. Because thou hast rejected the word of the LORD, He hath also rejected thee from being king. And Saul said unto Samuel, I have sinned: for I have transgressed the commandment of the LORD, and thy words: because I feared the people, and obeyed their voice.
