1 Samuel 12:13-15

13Now here is the king you have chosen, the one you asked for; see, the LORD has set a king over you. 14If you fear the LORD and serve and obey him and do not rebel against his commands, and if both you and the king who reigns over you follow the LORD your God—good!

15But if you do not obey the LORD, and if you rebel against his commands, his hand will be against you, as it was against your ancestors.
