John 16:18

They said therefore,.... One, and all of them; the inquiry became universal;

what is this that he saith, a little while? it seems as if this phrase was the most intricate and perplexing to them; for whatever conceptions they might have of not seeing, and seeing him again, as expressive of his going from them, and returning to them, yet had no notion at all what he should mean by "a little while": and therefore add,

we cannot tell what he saith: they knew his words, but not his meaning.
