'Deceiver' in the Bible

“With Him are might and sound wisdom,The misled and the misleader are His [and in His power].

“Let everyone beware of his neighborAnd do not trust any brother.For every brother is a supplanter [like Jacob, a deceiver, ready to grab his brother’s heel],And every neighbor goes around as a slanderer.

“But cursed is the swindler who has a male in his flock and vows [to offer] it, but sacrifices to the Lord a blemished or diseased thing! For I am a great King,” says the Lord of hosts, “and My name is to be [reverently and greatly] feared among the nations.”

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].

And the great dragon was thrown down, the age-old serpent who is called the devil and Satan, he who continually deceives and seduces the entire inhabited world; he was thrown down to the earth, and his angels were thrown down with him.
