Jesus answered them
The disciples, taking Peter's answer to his question, as
delivered in the name of them all, and as expressing their mind
and sense:
have not I chosen you twelve;
not to grace and glory, to holiness and happiness; though this
was true of eleven of them, but to be apostles:
and one of you is a devil?
or like to one, is a deceiver, a liar, and a murderer, as the
devil is from the beginning; all which Judas was, and appeared to
be, in the betraying of his master. The Syriac, Persic, and
Ethiopic versions read, "is Satan"; which name, if given to
Peter, as it once was on a certain occasion, ( Matthew
16:23 ) , might very well be given to Judas; who,
notwithstanding his profession of faith in Christ, was in the
hands and kingdom of Satan, and under his influence and power:
and this our Lord said, partly that they might not too much
presume upon their faith and love, and steady attachment, and be
over confident of their standing; and partly, to prepare them for
the apostasy of one from among them.
