1 Samuel 15:19-23

19Why then did you not obey the voice of the Lord? Why did you swoop down on the spoil, and do evil in the sight of the Lord?”

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

21But the people took of the plunder, sheep and oxen, the best of the things which should have been utterly destroyed, to sacrifice to the Lord your God in Gilgal.”

22So Samuel said: “Has the Lord as great 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.

23For rebellion is as the sin of witchcraft, And stubbornness is as iniquity and idolatry. Because you have rejected the word of the Lord, He also has rejected you from being king.”
