1 Samuel 15:22-24

But Samuel replied, “What is more pleasing to the LORD: your burnt offerings and sacrifices or your obedience to his voice? Listen! Obedience is better than sacrifice, and submission is better than offering the fat of rams. Rebellion is as sinful as witchcraft, and stubbornness as bad as worshiping idols. So because you have rejected the command of the LORD, he has rejected you as king.” Then Saul admitted to Samuel, “Yes, I have sinned. I have disobeyed your instructions and the LORD’s command, for I was afraid of the people and did what they demanded.
