Jeremiah 18:6 (KJV)

The word which came to Jeremiah from the LORD, saying,

Arise, and go down to the potter's house, and there I will cause thee to hear my words.

Then I went down to the potter's house, and, behold, he wrought a work on the wheels.

And the vessel that he made of clay was marred in the hand of the potter: so he made it again another vessel, as seemed good to the potter to make it.

Then the word of the LORD came to me, saying,

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

If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them.

And at what instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant it;

If 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.

Now therefore go to, speak to the men of Judah, and to the inhabitants of Jerusalem, saying, Thus saith the LORD; Behold, I frame evil against you, and devise a device against you: return ye now every one from his evil way, and make your ways and your doings good.
