1 Samuel 12:16-18

12:16 “So now, take your positions and watch this great thing that the Lord is about to do in your sight. 12:17 Is this not the time of the wheat harvest? I will call on the Lord so that he makes it thunder and rain. Realize and see what a great sin you have committed before the Lord by asking for a king for yourselves.”

12:18 So Samuel called to the Lord, and the Lord made it thunder and rain that day. All the people were very afraid of both the Lord and Samuel.
