1 Samuel 15:19-23

19Why then did you not obey the voice of Adonai, but rushed greedily onto the spoil—doing what was evil in Adonai’s eyes?”

20“But I did obey the voice of Adonai,” Saul said to Samuel. “I went on the mission on which Adonai sent me, and brought back Agag the king of Amalek—and utterly destroyed the Amalekites.

21But the people took some of the spoil, sheep and oxen—the best of what was under the ban of destruction— to sacrifice to Adonai your God in Gilgal.”

22Samuel said: “Does Adonai delight in burnt offerings and sacrifices as in obeying the voice of Adonai? Behold, to obey is better than sacrifice, to pay heed than the fat of rams.

23For rebellion is like the sin of divination and stubbornness is like iniquity and idolatry. Since you have rejected Adonai’s word, He has also rejected you as king.”
