1 Samuel 15:19-23

Why then did you not obey the voice of the Lord? Instead, you loudly rushed upon the spoils and did what was evil in the sight of the Lord!”

Then Saul said to Samuel, “I did obey the voice of the Lord, for I went on the mission on which the Lord sent me; and I have brought Agag the king of Amalek, and have completely destroyed the Amalekites.

But the people took some of the spoils, sheep and oxen, the choicest of the things designated for destruction, to sacrifice to the Lord your God at Gilgal.”

Samuel said, “Does the Lord have as much delight in burnt offerings and sacrifices As in obeying the voice of the Lord? Behold, to obey is better than a sacrifice, And to pay attention is better than the fat of rams.

“For rebellion is as reprehensible as the sin of divination, And insubordination is as reprehensible as false religion and idolatry. Since you have rejected the word of the Lord, He has also rejected you from being king.”
