1 Samuel 15:19-23

19Why did you not obey the voice of the Lord, but [instead] swooped down on the plunder [with shouts of victory] and did evil in the sight of the Lord?”

20Saul said to Samuel, “I have obeyed the voice of the Lord, and have gone on the mission on which the Lord sent me, and have brought back Agag the king of Amalek, and have completely destroyed the Amalekites.

21But the people took some of the spoil, sheep and oxen, the best of the things [that were] to be totally destroyed, to sacrifice to the Lord your God at Gilgal.”

22Samuel 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.

23For 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.”
