The New John Gill Exposition of the Entire BibleActs 2:12
And they were all amazed…
That is, all these devout
men, Jews and proselytes, which came from other nations before
and were in doubt;
not whether the apostles spoke in various
languages, nor about the sense of their words; for they not only
heard them with their ears, and were assured of the facts, but they
seem also to understand what was said, since they call the things
delivered, the great or wonderful things of God; but they were at a
loss in their minds what should be the cause of this, or the reason
of such a dispensation,
saying, one to another, what meaneth this?
from whence is it? what
is the design of it? or what the end to be answered by it? or what
will follow upon it? surely something considerable.
