The sense is: God’s prophet has declared that a great national calamity is at hand. “Make inquiries; stand in the ways; ask the passers by. Your country was once prosperous and blessed. Try to learn what were the paths trodden in those days which led your ancestors to happiness. Choose them, and walk earnestly therein, and find thereby rest for your souls.” The Christian fathers often contrast Christ the one goodway with the old tracks, many in number and narrow to walk in, which are the Law and the prophets.
