Hear how, and on what principle. There is a law ordained of God, recited by Jeremiah, the prophet to the Jews, and in these words: “At what instant I shall speak a sentence concerning a nation and kingdom, to pluck up and destroy; if that nation turn from their evil deeds, I also will repent of the evils, which I thought to do unto them. And at what instant I shall speak concerning a nation and kingdom to build and to plant it; and if they do evil in my sight, that they obey not my voice, I also will repent of the good, which I said I would do unto them.”
