Thematic Bible: Rain and thunder

So stand still and see this great thing the Lord will do before your eyes now. Is it not wheat harvest today? I will call to the Lord and He will send thunder and rain; then you shall know and see that your wickedness is great which you have done in the sight of the Lord in asking for a king for yourselves. So Samuel called to the Lord, and He sent thunder and rain that day; and all the people greatly feared the Lord and Samuel.
