For he whom God hath sent. — Better, he whom God sent. The acceptance of the witness of things seen and heard is the attestation by the human spirit of the truthfulness of God, for Jesus is as one sent from God to declare Him. It is the divine image in man which recognises divinity. Every human faculty finds its true work, and true satisfaction, and the true object of its being, in Him; and therefore the whole man knows that His words are true, and recognises that He speaks the words of God. (Comp. 1 John 5:10.)
For God giveth not the Spirit by measure unto him. — The italics will show that the words “unto Him” are added in our version; and it is probable that the word “God,” which has been repeated from the first clause of the verse, should be also omitted here. We have then to read, “For He giveth not the Spirit by measure;” or, possibly, “For the Spirit giveth not by measure.” If, however, we remember that John the Baptist is the speaker, and that he had seen “the Spirit of God descending like a dove, and coming upon Him” (see Note on Matthew 3:16, and comp. such passages as Luke 11:13, and in this Gospel John 14:16; John 15:26), we shall still interpret the words in the sense which our version gives. The words “by measure,” in the sense of limitation, are frequent in the classical and rabbinical writings. The Rabbis seem to have applied the phrase to prophets and teachers, saying that the Spirit dwelt in the prophets only in a certain measure. Comp. 2 Kings 2:9, where Elisha prays for “a double portion,” or, more exactly, a portion of two — the portion of the first-born son (Deuteronomy 21:17) — of the spirit of Elijah. The same thought meets us in St. Paul (himself a pupil of Gamaliel), who speaks of “the self-same Spirit dividing to every man severally as He will” (see 1 Corinthians 12:4-12). The opposite of this thought, then, is before us here. God gives in this case not as in others. The Son who cometh from above is above all. There is no gift of prophet, or of teacher, which is not given to Him. He has the fulness of the spiritual gifts which in part are given to men, and He speaks the very words of God. It will be noted that John is still expounding to his disciples the meaning of his own declaration, “He must increase, but I must decrease.”
