For rebellion [is as] the sin of witchcraft, and stubbornness [is as] iniquity and idolatry. Because thou hast rejected the word of the LORD, he hath also rejected thee from [being] king.
Berean Study Bible (BSB) - 1 Samuel 15:23 >For rebellion is like the sin of divination, and arrogance is like the wickedness of idolatry. Because you have rejected the word of the LORD, He has rejected you as king.”
