I also will ask you one thing. — The question is met by another question. As One who taught as “having authority, and not as the scribes” (Matthew 7:29), He challenges their right to interrogate Him on the ground of precedent. Had they exercised that right in the case of the Baptist, and if so, with what result? If they had left his claim unquestioned, or if they had shrunk from confessing the result of their inquiry, they had virtually abdicated their office, and had no right, in logical consistency, to exercise it, as by fits and starts, in the case of another teacher.
