But have nothing to do with irreverent folklore and silly myths. On the other hand, discipline yourself for the purpose of godliness [keeping yourself spiritually fit].

and will turn their ears away from the truth and will wander off into myths and man-made fictions [and will accept the unacceptable].

Giving no attention to the fictions of the Jews and the rules of men who have no true knowledge.
