1 Samuel 15:19-23 Catholic Public Domain Version (CPDV)

19. Why then, did you not listen to the voice of the Lord? Instead, you turned to the spoils, and you did evil in the eyes of the Lord."

20. And Saul said to Samuel: "On the contrary, I did listen to the voice of the Lord, and I walked in the way along which the Lord sent me, and I led back Agag, the king of Amalek, and I put to death Amalek.

21. But the people took some of the spoils, sheep and oxen, as the first-fruits of those things that were slain, to immolate to the Lord their God at Gilgal."

22. And Samuel said: "Does the Lord want holocausts and victims, and not instead that the voice of the Lord should be obeyed? For obedience is better than sacrifice. And to heed is greater than to offer the fat of rams.

23. Therefore, it is like the sin of paganism to rebel. And it is like the crime of idolatry to refuse to obey. For this reason, therefore, because you have rejected the word of the Lord, the Lord has also rejected you from being king."
