1 Samuel 12:16-18

16Now stand where you are and watch! The Lord will do a great thing and you will see it.

17This is the time of the wheat harvest. I will ask the Lord to send thunder and rain. Then you will understand that you have done an evil thing against the Lord. You asked for a king to rule over you.’

18Samuel prayed to the Lord. That same day the Lord sent thunder and rain. All the people became afraid of the Lord and of Samuel.
