Jesus answered and said unto them, (b) Though I bear record of myself, [yet] my record is true: for I know whence I came, and whither I go; but ye cannot tell whence I come, and whither I go.
(b) That which he denied before in (John 5:31) must be understood as Christ granting their position in a way, for in that place he talked of himself somewhat in line with the opinions of his hearers, who acknowledged nothing in Christ but his humanity, and therefore he was content they should not regard his own witness, unless it were otherwise confirmed. But in this place he stands and affirms Godhead, and praises his Father, who is his witness, and agrees with him.
