Heaven's Thunder

And when you saw that Nahash the king of the Ammonites came against you, you said to me, 'No, but a king shall reign over us,' when the LORD your God was your king. [13] And now behold the king whom you have chosen, for whom you have asked; behold, the LORD has set a king over you. [14] If you will fear the LORD and serve him and obey his voice and not rebel against the commandment of the LORD, and if both you and the king who reigns over you will follow the LORD your God, it will be well. [15] But if you will not obey the voice of the LORD, but rebel against the commandment of the LORD, then the hand of the LORD will be against you and your king. [16] Now therefore stand still and see this great thing that the LORD will do before your eyes. [17] Is it not wheat harvest today? I will call upon the LORD, that he may send thunder and rain. And you shall know and see that your wickedness is great, which you have done in the sight of the LORD, in asking for yourselves a king." [18] So Samuel called upon the LORD, and the LORD sent thunder and rain that day, and all the people greatly feared the LORD and Samuel. (1 Samuel 12:12–18, ESV
