'Legends' in the Bible

nor to pay attention to legends (fables, myths) and endless genealogies, which give rise to useless speculation and meaningless arguments rather than advancing God’s program of instruction which is grounded in faith [and requires surrendering the entire self to God in absolute trust and confidence].

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 not give attention to Jewish legends and the maxims of men who turn their backs on the truth.

For when we made known to you the power and Coming of our Lord Jesus Christ, we were not eagerly following cleverly devised legends, but we had been eye-witnesses of His majesty.
