First Shmuel 15:22-23:
[To King Shaul]
22 Has YHV as great delight in burnt offerings and sacrifices, as in obedience to the voice of YHV? Behold: to obey is better than sacrifice, and to hearken than the fat of rams.
23 For rebellion [against YHV] is as the misdeed of witchcraft, and stubbornness is as iniquity and idolatry. Because you have rejected the word of YHV, He has rejected you as King of Israel.
Something for all Israelites to bear in mind.
