John 8:13-14

{5} The Pharisees therefore said unto him, {a} Thou bearest record of thyself; thy record is not true.

(5) Christ is without all exception the best witness of the truth, for he was sent by his Father for that purpose, and his Father showed his approval of him to the world by infinite miracles. (a) You bear witness of yourself, which is worth nothing in the opinion of all men, and for a man to commend himself is very uncommendable.
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 Joh 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.
