1 Samuel 15:3

15:3 So go now and strike down the Amalekites. Destroy everything that they have. Don’t spare them. Put them to death – man, woman, child, infant, ox, sheep, camel, and donkey alike.’”

1 Samuel 15:22-23

15:22 Then Samuel said,

“Does the Lord take pleasure in burnt offerings and sacrifices

as much as he does in obedience?

Certainly, obedience is better than sacrifice;

paying attention is better than the fat of rams.

15:23 For rebellion is like the sin of divination,

and presumption is like the evil of idolatry.

Because you have rejected the word of the Lord,

he has rejected you as king.”
