1 Samuel 12:16-18

King James Version

¹⁶ Now therefore stand and see this great thing, which the Lord will do before your eyes.

¹⁷ Is it not wheat harvest to day? I will call unto the Lord, and he shall send thunder and rain; that ye may perceive and see that your wickedness is great, which ye have done in the sight of the Lord, in asking you a king.

¹⁸ So Samuel called unto the Lord; and the Lord sent thunder and rain that day: and all the people greatly feared the Lord and Samuel.
