6. All this is ratified by the divine authority and veracity: I the Lord have spoken it, v. 15 and again v. 17. The sentence is passed by him that is Judge of heaven and earth, whose judgment is according to truth, and the judgments of whose hand are according to the judgments of his mouth. He has spoken it who can do it, for with him nothing is impossible. He has spoken it who will do it, for he is not a man that he should lie. He has spoken it whom we are bound to hear and heed, whose ipse dixit—word commands the most serious attention and submissive assent: And they shall know that I the Lord have spoken it, v. 13. There were those who thought it was only the prophet that spoke it in his delirium; but God will make them know, by the accomplishment of it, that he has spoken it in his zeal. Note, Sooner or later, God's word will prove itself.
