Jeremiah 28:11

And Hananiah spake in the presence of all the people, saying, in another base falsehood. Thus saith the Lord, Even so will I break the yoke of Nebuchadnezzar, king of Babylon, from the neck of all nations within the space of two full years. He thought that the bold repetition of his false prophecy, together with the symbolic act which accompanied it, would cause the people to believe him without question. And the prophet Jeremiah went his way, leaving the justification of his prophecy to the Lord for the present. In many cases it is the part of true wisdom for believers not to reply to bold statements on the part of the adversaries, but to leave the vindication of the Lord's honor to the Lord Himself.
