1 Samuel 15:13-14, 22-23

Samuel came to Saul, and Saul said to him, “Blessed are you of the LORD! I have carried out the command of the LORD.” But Samuel said, “What then is this bleating of the sheep in my ears, and the lowing of the oxen which I hear?”

Samuel said, “Has the LORD as much delight in burnt offerings and sacrifices As in obeying the voice of the LORD? Behold, to obey is better than sacrifice, And to heed than the fat of rams. For rebellion is as the sin of divination, And insubordination is as iniquity and idolatry. Because you have rejected the word of the LORD, He has also rejected you from being king.”
