1 Samuel 15:20-22

Then Saul said to Samuel, “I did obey the voice of the LORD, and went on the mission on which the LORD sent me, and have brought back Agag the king of Amalek, and have utterly destroyed the Amalekites. But the people took some of the spoil, sheep and oxen, the choicest of the things devoted to destruction, to sacrifice to the LORD your God at Gilgal.” Samuel said, “Has the LORD as much 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.
