Jamieson, Fausset and Brown on John 16:16-22

16-22. A little while, and ye shall not see me; and again a little while, and ye shall see me, because I go to the Father--The joy of the world at their not seeing Him seems to show that His removal from them by death was what He meant; and in that case, their joy at again seeing Him points to their transport at His reappearance amongst them on His Resurrection, when they could no longer doubt His identity. At the same time the sorrow of the widowed Church in the absence of her Lord in the heavens, and her transport at His personal return, are certainly here expressed.
