1 Samuel 15:21-23

Modern English Version

“Does the Lord delight in burnt offerings and sacrifices
    as much as in obeying the voice of the Lord?
Obedience is better than sacrifice,
    a listening ear than the fat of rams.
²³ For rebellion is as the sin of witchcraft,
    and stubbornness is as iniquity and idolatry.
Because you have rejected the word of the Lord,
    He has also rejected you from being king.”
