1 Samuel 15:22-23 AMP
[22] Samuel said, “Has the Lord as great a delight in burnt offerings and sacrifices As in obedience to the voice of the Lord? Behold, to obey is better than sacrifice, And to heed [is better] than the fat of rams. [23] For rebellion is as [serious as] the sin of divination (fortune-telling), And disobedience is as [serious as] false religion and idolatry. Because you have rejected the word of the Lord, He also has rejected you as king.”
