5 Then the word of the Lord came to me: 6Can I not do with you, O house of Israel, just as this potter has done? says the Lord. Just like the clay in the potter’s hand, so are you in my hand, O house of Israel. 7At one moment I may declare concerning a nation or a kingdom, that I will pluck up and break down and destroy it, 8but if that nation, concerning which I have spoken, turns from its evil, I will change my mind about the disaster that I intended to bring on it. 9And at another moment I may declare concerning a nation or a kingdom that I will build and plant it, 10but if it does evil in my sight, not listening to my voice, then I will change my mind about the good that I had intended to do to it. 11Now, therefore, say to the people of Judah and the inhabitants of Jerusalem: Thus says the Lord: Look, I am a potter shaping evil against you and devising a plan against you. Turn now, all of you from your evil way, and amend your ways and your doings. --Jeremiah 18:5-11 NRSV http://bible.oremus.org/?passage=Jeremiah+18
4Jonah began to go into the city, going a day’s walk. And he cried out, ‘Forty days more, and Nineveh shall be overthrown!’ 5And the people of Nineveh believed God; they proclaimed a fast, and everyone, great and small, put on sackcloth.
6 When the news reached the king of Nineveh, he rose from his throne, removed his robe, covered himself with sackcloth, and sat in ashes. 7Then he had a proclamation made in Nineveh: ‘By the decree of the king and his nobles: No human being or animal, no herd or flock, shall taste anything. They shall not feed, nor shall they drink water. 8Human beings and animals shall be covered with sackcloth, and they shall cry mightily to God. All shall turn from their evil ways and from the violence that is in their hands. 9Who knows? God may relent and change his mind; he may turn from his fierce anger, so that we do not perish.’10 When God saw what they did, how they turned from their evil ways, God changed his mind about the calamity that he had said he would bring upon them; and he did not do it. --Jonah 3: 4-10 NRSV http://bible.oremus.org/?passage=Jonah+3
