1 Samuel 12:16-20

16So now, take your stand and see this great thing which the Lord will do before your eyes.

17Is it not [the beginning of the] wheat harvest today? I will call to the Lord and He will send thunder and rain; then you will know [without any doubt], and see that your evil which you have done is great in the sight of the Lord by asking for yourselves a king.”

18So Samuel called to the Lord [in prayer], and He sent thunder and rain that day; and all the people greatly feared the Lord and Samuel.

19Then all the people said to Samuel, “Pray to the Lord your God for your servants, so that we will not die, for we have added to all our sins this evil—to ask for a king for ourselves.”

20Samuel said to the people, “Do not be afraid. You have [indeed] done all this evil; yet do not turn away from following the Lord, but serve the Lord with all your heart.
