2 John 1:7

For many deceivers are entered into the world,.... By whom are meant false teachers, who are described by their quality, "deceivers", deceitful workers, pretending to be ministers of Christ, to have a: value for truth, a love for souls, and a view to the glory of God, but lie in wait to deceive, and handle the word of God deceitfully; and by their quantity or number, "many", and so likely to do much mischief; and by the place where they were, they were "entered into the world"; or "gone out into the world", as the Alexandrian copy and some others, and the Vulgate Latin and Syriac versions read; See Gill on "1Jo 4:1"; and by their tenet,who confess not that Jesus Christ is come in the flesh; these were not the Jews who denied that Jesus was the Christ, though they would not allow that Christ was come in the flesh; but these were some who bore the Christian name, and professed to believe in Jesus Christ, but would not own that he was really incarnate, or assumed a true human nature, only in appearance; and denied that he took true and real flesh of the virgin, but only seemed to do so; and these are confuted by the apostle, 1Jo 1:1; and upon everyone of these he justly fixes the following character.
