'Imposter' in the Bible

Suppose my father touches me and feels my skin; then I will be seen by him as a cheat (imposter), and I will bring his curse on me and not a blessing.”

and said, “Sir, we have remembered that when He was still alive that deceiver said, ‘After three days I will rise [from the dead].’

For many deceivers [heretics, posing as Christians] have gone out into the world, those who do not acknowledge and confess the coming of Jesus Christ in the flesh (bodily form). This [person, the kind who does this] is the deceiver and the antichrist [that is, the antagonist of Christ].
