Charles Ellicott Commentary John 16:5

"But now I go unto him that sent me; and none of you asketh me, Whither goest thou?" — John 16:5 (ASV)

But now I go my way to him that sent me.—(John 14:12). The work of His apostleship on earth was drawing to its close, and He was about to return to the Father from whom He had received it. This was to Him matter of joy, and if they had really loved Him would have been so to them. They would have thought of the future before Him, as He was then thinking, in the fullness of His love, of the future before them.

And none of you asketh me, Whither goest thou?—Peter had asked this very question (John 13:36), and Thomas had implied it (John 14:5), but what the words here mean is, “None of you are out of love for Me asking about the place where I am going. Your thoughts are not with Me. It is to you as nothing that I am returning to Him that sent Me.”
