1st Samuel 12:16

13 Now therefore behold the king whom ye have chosen, and whom ye have desired! and, behold, the LORD hath set a king over you.

14 If ye will fear the LORD, and serve him, and obey his voice, and not rebel against the commandment of the LORD, then shall both ye and also the king that reigneth over you continue following the LORD your God:

15 But if ye will not obey the voice of the LORD, but rebel against the commandment of the LORD, then shall the hand of the LORD be against you, as it was against your fathers.

16 Now therefore stand and see this great thing, which the LORD will do before your eyes.

17 Is it not wheat harvest to day? I will call unto the LORD, and he shall send thunder and rain; that ye may perceive and see that your wickedness is great, which ye have done in the sight of the LORD, in asking you a king.

18 So Samuel called unto the LORD; and the LORD sent thunder and rain that day: and all the people greatly feared the LORD and Samuel.

19 And all the people said unto Samuel, Pray for thy servants unto the LORD thy God, that we die not: for we have added unto all our sins this evil, to ask us a king.
