1 Samuel 15:21

19Why then didn’t you obey the LORD’s voice, but took the plunder, and did that which was evil in the LORD’s sight?”

20Saul said to Samuel, “But I have obeyed the LORD’s voice, and have gone the way which the LORD sent me, and have brought Agag the king of Amalek, and have utterly destroyed the Amalekites.

21But the people took of the plunder, sheep and cattle, the best of the devoted things, to sacrifice to the LORD your God in Gilgal.”

22Samuel said, “Has the LORD as great delight in burnt offerings and sacrifices, as in obeying the LORD’s voice? Behold, to obey is better than sacrifice, and to listen than the fat of rams.

23For rebellion is as the sin of witchcraft, and stubbornness is as idolatry and teraphim. Because you have rejected the LORD’s word, he has also rejected you from being king.”
