Samuel said, Has Yahweh as great delight in burnt offerings and sacrifices, as in obeying the voice of Yahweh? Behold, to obey is better than sacrifice, and to listen than the fat of rams.
For the Lord said, I remember the Amaleks that when you were trying to come into the land, they withstood you. And therefore God wants you to go down and utterly wipe out the Amaleks; every man, woman, child, animal. [Don't take anything back alive, utterly slay everything] ( 1 Samuel 15:2-3 ).
