1 Samuel 15:19-23

19Why haven’t you obeyed the Lord? Instead you have greedily rushed upon the plunder! You have done what is wrong in the Lord’s estimation.”

20Then Saul said to Samuel, “But I have obeyed the Lord! I went on the campaign the Lord sent me on. I brought back King Agag of the Amalekites after exterminating the Amalekites.

21But the army took from the plunder some of the sheep and cattle – the best of what was to be slaughtered – to sacrifice to the Lord your God in Gilgal.”

22Then Samuel said, “Does the Lord take pleasure in burnt offerings and sacrifices as much as he does in obedience? Certainly, obedience is better than sacrifice; paying attention is better than the fat of rams.

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