'Fictions' in the Bible

Should thy fictions make men hold their peace? and shouldest thou mock, and no one make thee ashamed?

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.
