But know ye for certain— This is Jeremiah's justification of himself. He reduces all to the proof that God had sent him; and his adversaries were able to make no reply. "If God hath sent me, you can have nothing to say against me." It is upon this that he is declared innocent, Jeremiah 26:16. This man is not worthy to die. See Calmet.
