1Ti 4:7 but refuse profane and old wives' fables. And exercise thyself to godliness:

1Ti 4:1 But the Spirit saith expressly, that in later times some shall fall away from the faith, giving heed to seducing spirits and doctrines of demons,
1Ti 4:2 through the hypocrisy of men that speak lies, branded in their own conscience as with a hot iron;

Mat 7:15 Beware of false prophets, who come to you in sheep's clothing, but inwardly are ravening wolves.
Mat 7:16 By their fruits ye shall know them. Do men gather grapes of thorns, or figs of thistles?
Mat 7:17 Even so every good tree bringeth forth good fruit; but the corrupt tree bringeth forth evil fruit.
Mat 7:18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
Mat 7:19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
Mat 7:20 Therefore by their fruits ye shall know them.
