The most peculiar prophecy about the man of sin (antichrist) was written by the prophet Daniel.

He warned:  "He shall regard  neither the God of his Fathers nor the desire of women, nor regard any god; for he shall   magnify himself above them all"   Daniel 11:37.

This vision is puzzling but it would confirm that the Antichrist will be a Jew since it declares he won't have regard for the God of his Fathers.

That is an expression used in the Bible only in connection with the Jews.
