(61) When Jesus knew in himself that his disciples murmured.--The tenses in the original describe the scene in the present: Jesus as knowing, the disciples as murmuring. The knowledge is in Himself, uninformed by them, and His teaching is addressed to the thoughts of their hearts. They were placing themselves in the position of the Jews (John 6:41), and were making the stepping-stone of spiritual knowledge, up which faith would have walked, into a rock of offence over which blindness fell.

Verse 61. - But Jesus, knowing in himself - not necessarily by supernatural penetration, for many signs of impatience may have been manifested - that his disciples murmured (see ver. 41, note) concerning this hard argument, said unto them, Doth this cause you to stumble? (see note on John 16:1).

6:60-65 The human nature of Christ had not before been in heaven, but being God and man, that wondrous Person was truly said to have come down from heaven. The Messiah's kingdom was not of this world; and they were to understand by faith, what he had said of a spiritual living upon him, and his fulness. As without the soul of man the flesh is of no value, so without the quickening Spirit of God all forms of religion are dead and worthless. He who made this provision for our souls, alone can teach us these things, and draw us unto Christ, that we may live by faith in him. Let us apply to Christ, thankful that it is declared that every one who is willing to come unto him shall be made welcome.When Jesus knew in himself,.... And of himself, without any intelligence from others, or hearing what was said, being the omniscient God:

that his disciples murmured at it; at the doctrine he had delivered, looking upon it as absurd, incredible, and contrary to sense and reason:

he said unto them, does this offend you? or trouble you? cannot you get over this? cannot you understand it? or account for it? if not, how will you be able to digest some other things, or reconcile them to your minds, which are less known, and more unexpected, and will appear at first sight more surprising?
