1 Samuel 12:22 (KJV)

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.

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.

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.

And Samuel said unto the people, Fear not: ye have done all this wickedness: yet turn not aside from following the LORD, but serve the LORD with all your heart;

And turn ye not aside: for then should ye go after vain things, which cannot profit nor deliver; for they are vain.

Moreover as for me, God forbid that I should sin against the LORD in ceasing to pray for you: but I will teach you the good and the right way:

Only fear the LORD, and serve him in truth with all your heart: for consider how great things he hath done for you.

But if ye shall still do wickedly, ye shall be consumed, both ye and your king.
