1 Samuel 15:22-23

Then Samuel said, Do you think all GOD wants are sacrifices— empty rituals just for show? He wants you to listen to him! Plain listening is the thing, not staging a lavish religious production. Not doing what GOD tells you is far worse than fooling around in the occult. Getting self-important around GOD is far worse than making deals with your dead ancestors. Because you said No to GOD’s command, he says No to your kingship.
