1 Samuel 12:16-18

“Now then, stand still and see this great thing the LORD is about to do before your eyes! Is it not wheat harvest now? I will call on the LORD to send thunder and rain. And you will realize what an evil thing you did in the eyes of the LORD when you asked for a king.” Then Samuel called on the LORD, and that same day the LORD sent thunder and rain. So all the people stood in awe of the LORD and of Samuel.
