2 Timothy 3:6 - 3:9
6 For among them are those who enter into households and take captive weak women weighed down with sins, being led on by various desires, 7 always learning and never able to come to the full knowledge of the truth. 8 Just as Jannes and Jambres opposed Moses, so these men also oppose the truth, men of depraved mind, disqualified in regard to the faith. 9 But they will not make further progress, for their folly will be obvious to all, just as theirs was also.
