Whoso boasteth himself of a false gift
Of his charity and alms deeds; bragging of great things he does
this way, when he does nothing; or who is very vain in making
large promises of what he will give, when he does not perform;
either not having it in his heart, or in the power of his hands,
to give what he promises; Satan like, who offered to give all the
kingdoms of this world to Christ, if he would worship him, when
nothing of it belonged unto him, or was in his power to give: and
so the Vulgate Latin version renders it, "a glorious man"; that
is, a vainglorious man, and "not fulfilling promises". It may
very well be applied to false teachers, who boast of their gifts
and spiritual knowledge, when they have none; speaking great
swelling words of vanity, when they are empty of all that is
good, and are as follow: [is like] like clouds and wind
without rain;
which make a show and appearance of rain, promise much, but
produce none; see ( 2 Peter 2:17
2 Peter
2:18 ) ( Jude 1:12 ) .
