But refuse profane and old wives' fables. Exercise yourself toward godliness.
Fables - Fictions, or stories that were not founded on fact. The pagan religion abounded with fictions of this kind, and the Jewish teachers were also remarkable for the number of such fables which they had introduced into their system. It is probable that the apostle referred here particularly to the Jewish fables, and the counsel which he gives to Timothy is, to have nothing to do with them.
