1 Samuel 15:22-23

And Samuel said, Hath Jehovah as great delight in burnt-offerings and sacrifices, as in obeying the voice of Jehovah? 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 idolatry and teraphim. Because thou hast rejected the word of Jehovah, he hath also rejected thee from being king.
