Jeremiah 18:7-10

7At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up and to break down and to destroy it; 8if that nation, concerning which I have spoken, turn from their evil, I will repent of the evil that I thought to do unto them. 9And at what instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant it; 10if they do that which is evil in my sight, that they obey not my voice, then I will repent of the good, wherewith I said I would benefit them.
