Deuteronomy 4:32 - Ellicott's Commentary On The Whole Bible

For ask now... whether there hath been any such thing.-The same argument is afterwards employed by St. Paul (Romans 11:29) for the restoration of Israel: “for the gifts and calling of God are without repentance,” i.e., irrevocable. He did not go and take Him a nation out of the midst of another nation in order to abandon them at last. He never did so much in the way of personal and visible interposition for any people; and He will not forsake the work of His own hands. Moses had proved the truth of what he says here in many scenes of sin and peril averted by his own intercession. (See especially Numbers 14:11-21, and comp. 1 Samuel 12:22.)
