John 8:42 - Coke's Commentary on the Holy Bible

I proceeded forth and came from God;— "I originally proceeded from God the Father as his only-begotten Son, partaker of the same nature with him, and am come into the world immediately from him: I did not come merely of myself, like a false prophet, but by commission from him, who sent me, as the Messiah, to make known the way of salvation, and to do his will upon earth." We must observe the difference between what Christ here says of himself, and what is ever said of any other: believers are said to be of God, John 8:47 and 1 John 4:4 and to be born and begotten of God, 1 John 5:1 and the prophets were said to be sent of God, as John the Baptist also was, John 1:6. But it is peculiar to Christ, that he proceeded forth, and came from God, which intimates his divine original, as well as mission; that he is of the Father as a Son of his own essence, proceeding from him; as well as that he came from the Father, as a divine messenger: for the form of expression, εγω εκ του Θεου εξηλθον, here rendered I proceeded forth from God, is often used by the LXX to signify a proper birth, when applied to man; as in Genesis 15:4 it is said, he that shall come forth out of thine own bowels, shall be thine heir: also Genesis 35:11. Kings shall come out of thy loins. And it is said of Christ with respect to his human birth, Isaiah 11:1 there shall come forth a rod out of the stem of Jesus. The phraseology is the same in all these places, with that which is here rendered proceeding forth.
