Jeremiah 18:7-10

7At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy it;

8If that nation, against whom I have pronounced, 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 it do evil in my sight, that it obey not my voice, then I will repent of the good, wherewith I said I would benefit them.
