1 Samuel 12
17 Ref Is it not now the time of the grain cutting? My cry will go up to the Lord and he will send thunder and rain: so that you may see and be conscious of your great sin which you have done in the eyes of the Lord in desiring a king for yourselves.
18 Ref So Samuel made prayer to the Lord; and the Lord sent thunder and rain that day: and all the people were in fear of the Lord and of Samuel.
