1 Samuel 12:10-14

They cried out to the Lord and said, ‘We have sinned, because we have abandoned the Lord and have served the Baals and the Ashtaroth; but now save us from the hands of our enemies, and we will serve You.’

Then the Lord sent Jerubbaal, Bedan, Jephthah, and Samuel, and saved you from the hands of your enemies all around, so that you lived in security. The King Confirmed

But when you saw that Nahash the king of the sons of Ammon was coming against you, you said to me, ‘No, but a king shall reign over us!’ Yet the Lord your God was your king.

And now, behold, the king whom you have chosen, whom you have asked for, and behold, the Lord has put a king over you.

If you will fear the Lord and serve Him, and listen to His voice and not rebel against the command of the Lord, then both you and the king who reigns over you will follow the Lord your God.
