The New John Gill Exposition of the Entire BibleJohn 16:19
Now Jesus knew that they were desirous to ask him…
This is a proof of Christ's deity, that he is the omniscient God who
knows all things, what is in man, even the secrets of the heart; for
he not only knew the whisperings of the disciples, and their
inquiries among themselves about the sense of his words, but also
their secret desires to ask him concerning it:
and said unto them, do ye inquire among yourselves of that I said, a
little while and ye shall not see me, and again a little while and ye
shall see me?
which he said before they could put the question to
him, they being bashful, and backward, through fear or shame; and
which not only confirms what is before observed of his omniscience,
but also shows his readiness to open his mind and meaning, and
explain himself to his disciples, as he does in the following words.
