Ye know whence I am - You have sufficient evidence of my divine mission, and that I am the Messiah.

Is true - Is worthy to be believed. He has given evidence that I came from him, and he is worthy to be believed. Many read this as a question - Do ye know me, and know whence I am? I have not come from myself, etc.

Ye both know me, and ye know whence I am - Perhaps they should be read interrogatively: Do ye both know me, and know whence I am? Our Lord takes them up on their own profession, and argues from it. Since you have got so much information concerning me, add this to it, to make it complete; viz. that I am not come of myself; am no self-created or self-authorized prophet; I came from God: - the testimony of John the Baptist, the descent of the Holy Ghost, the voice from heaven, the purity and excellence of my doctrine, and the multitude of my miracles, sufficiently attest this. Now, God is true who has borne testimony to me; but ye know him not, therefore it is that this testimony is disregarded.

Then cried Jesus in the temple as he taught,.... Overhearing the reasonings of these men, however, knowing what they said; so the Persic version adds, "having secretly known this"; exalted his voice as he was teaching in the temple, and in the midst of his discourse, publicly before all the people, in the temple, spoke out with a loud voice, that all might hear:

saying, ye both know me, and ye know whence I am; some, as the Ethiopic version, read these words by way of interrogation, "do ye both know me, and do ye know from whence I am?" no; you do not. Or they may be considered as an ironical concession; yes, you know me, and you know whence I am; you know me to be Jesus of Nazareth, but you are wrong, I am not of Nazareth; you suppose I come, from Galilee, but that is your ignorance; you take me to be the real son of Joseph, to be begotten by him on Mary, but that is your mistake: such is your knowledge of me: you know me indeed who I am, and from whence I come.

And I am not come of myself; into this world, by incarnation, or the assumption of human nature, to work out the salvation of men; the Father called him to it, and he agreeing to do it, was in the fulness of time sent about it; this was not a device of his own, or an honour he took to himself; he was not alone in it; it was a mutual agreement between him and his Father, in consequence of which he was sent and came.

But he that sent me is true; to the covenant he made with Christ, and to the promises he made to the fathers of the Old Testament, concerning the mission of his Son; and he is true to be believed, in the testimonies he gave of him, particularly by a voice from heaven, declaring him his beloved Son.

Whom ye know not; so that notwithstanding all their boasted knowledge of him, they knew not his Father, from whence he came, and by whom he was sent; and notwithstanding also their boasted knowledge of the one, only, true, and living God, see Romans 2:17; yet they knew him not in a spiritual sense; they knew him not in Christ, nor as the Father of Christ; they knew neither the Father nor the Son: and this their ignorance of both was the reason of their hatred of Christ, and of his followers, John 15:21.

Then (οὗν)

Rev., rightly, therefore, giving the reason for the succeeding words in Jesus' emotion awakened by the misconceptions of the people.

Cried (ἔκραξεν)

See on Mark 5:5; see on Mark 9:24.

As He taught (διδάσκων)

Better, Rev., teaching. The expression cried teaching implies speaking in a peculiarly solemn manner and with an elevation of voice.

Me - whence Iam

Conceding the truth of the people's statement in John 7:27, we know this man whence he is, so far as His outward person and His earthly origin were concerned. He goes on to show that they are ignorant of His divine relationship.

True (ἀληθινὸς)

True to the ideal of a sender: a genuine sender in the highest sense of the term. See on John 1:9.

{12} Then cried Jesus in the temple as he taught, saying, Ye both know me, and ye know whence I am: and I am not come of myself, but he that sent me is true, whom ye know not.

(12) The truth of Christ does not depend upon the judgment of man.

7:28 Ye know whence I am. This is a reply to their assertion that they did. If they really did they would know that he came from God. They did not even know God, or they would know him whom God sent.

7:28 Then cried Jesus - With a loud and earnest voice. Do ye both know me, and know whence I am ? - Ye do indeed know whence I am as a man. But ye know not my Divine nature, nor that I am sent from God.

28, 29. cried Jesus-in a louder tone, and more solemn, witnessing style than usual.

Ye both, &c.-that is, "Yes, ye know both Myself and My local parentage, and (yet) I am not come of Myself."

but he that sent me is true, &c.-Probably the meaning is, "He that sent Me is the only real Sender of any one."

7:25-30 Christ proclaimed aloud, that they were in error in their thoughts about his origin. He was sent of God, who showed himself true to his promises. This declaration, that they knew not God, with his claim to peculiar knowledge, provoked the hearers; and they sought to take him, but God can tie men's hands, though he does not turn their hearts.
