That frustrateth the tokens of the liars; i.e. "who brings to nought the prognostications of the astrologers and soothsayers, that pretend falsely to a knowledge of future events" (see Isaiah 49:13; and comp.
Jeremiah 29:8, Jeremiah 29:9); and maketh diviners mad; i.e. "shows them to be thole or madmen" (see Job 12:17). That turneth wise men backward; i.e. "repulses them—puts them to flight." Pretenders to wisdom, rather than truly wise men, are meant.
