However we know this man where he is from: but when Christ comes, no man knows where he is from.
All Commentaries on John 7:27 Go To John 7

AD 1849
We know this man whence he is. They looked upon him as no more than a man, and they thought they knew his father to be St. Joseph; they knew his Mother and kindred.
But when the Christ cometh, no man knoweth whence he is. Thus said some of the people; but, doubtless, the more learned knew Christ was to be born at Bethlehem. (Witham)
The Jews had imbibed this opinion of the secrecy of the origin of Christ from the prophet Isaias, Chap. liii. Who shall relate his generation? But they likewise were acquainted with many other texts of Scripture relative to the Messias, which plainly point out the place of his birth, viz. Bethlehem, and also the place of his residence, when it is said, He shall be called a Nazarite. His generation is indeed unknown with regard to his divinity, as Christ himself told the Jews in his answer: He is true that sent me, but you know him not. But as to his humanity, his origin is well known: You know me, and whence I am you know. (St. Augustine, tract. 31. in Joan.)
