1 Samuel 15:22-23

22But Samuel replied: “Does the LORD delight in burnt offerings and sacrifices as much as in obeying the LORD ? To obey is better than sacrifice, and to heed is better than the fat of rams.

23For rebellion is like the sin of divination, and arrogance like the evil of idolatry. Because you have rejected the word of the LORD, he has rejected you as king.”
