I Samuel 12:15-20

However, if you do not obey the voice of the LORD, but rebel against the commandment of the LORD, then the hand of the LORD will be against you, as it was against your fathers. “Now therefore, stand and see this great thing which the LORD will do before your eyes: Is today not the wheat harvest? I will call to the LORD, and He will send thunder and rain, that you may perceive and see that your wickedness is great, which you have done in the sight of the LORD, in asking a king for yourselves.” So Samuel called to 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 to Samuel, “Pray for your servants to the LORD your God, that we may not die; for we have added to all our sins the evil of asking a king for ourselves.” Then Samuel said to the people, “Do not fear. You have done all this wickedness; yet do not turn aside from following the LORD, but serve the LORD with all your heart.
