A.T. Robertson Commentary John 17:7

"Now they know that all things whatsoever thou hast given me are from thee:" — John 17:7 (ASV)

Now they know (νυν εγνωκαν). Perfect active indicative third plural like τετηρηκαν above. They have come to know, not as fully as they felt (16:30), and yet in a real sense.
