Jeremiah 25:13

And I will bring upon that land all My words which I have pronounced against it, carrying out His threats upon the entire country, even all that is written in this book, which Jeremiah hath prophesied against all the nations, for it was in this year that Jeremiah was, for the first time, told to write all his prophecies against the various foreign nations in a book, so that this remark was inserted when the collection was made.
