1 Samuel 15:21-23

The Voice

²¹It was the people who took the sheep and cattle from the spoil that would have been devoted to destruction and brought them back to sacrifice to the Eternal One, your True God, in Gilgal.

²²Samuel: Does the Eternal One delight in sacrifices and burnt offerings
        as much as in perfect obedience to His voice?
    Be certain of this: that obedience is better than sacrifice;
        to heed His voice is better than offering the fat of rams.
²³    Rebellion is as much a sin as fortune-telling,
        and willfulness is as wicked as worshiping strange gods.
    Because you have rejected His commands,
        He has rejected you as king.
