The New John Gill Exposition of the Entire BibleRevelation 13:9
If any man have an ear, let him hear.
] And diligently attend
to this mystical description of antichrist, as being matter of some
difficulty to understand, as well as of great moment and importance,
and seriously consider it, that he may know him, and his followers,
and avoid them; (See Gill on 1:7).
