And said unto him,.... By the disciples he sent; this was the message they came with, and this the question they were to ask, and did,art thou he that should come? A "periphrasis" of the Messiah, well known to the Jews; for he had been spoken of frequently in the prophecies of the Old Testament, as the Shiloh, the Redeemer, the Prophet, and King that should come; particularly, by this circumlocution, reference seems to be had to Hab 2:3.
"It shall surely come", aby ab yk, which may be rendered, "for he that cometh", or "is to come, shall come". So that the question in plain terms is, whether he was the Messiah? John could not be ignorant of this, who had seen the Spirit of God descending on him at his baptism, heard a voice from heaven, declaring him the Son of God; and had so often pointed him out to others, and had borne frequent testimonies that he was the Lamb of God, and bridegroom of his church: wherefore this question was put, not upon his own account, but his disciples, that they might have from the mouth of Christ a full and satisfactory answer, which would remove all their doubts and scruples, and attach them to Christ, now he was about to die, and leave them, than which nothing was more desirable to him.
Though some have thought, that John's faith was somewhat slackened; and through his long imprisonment, he began to doubt whether he was the Messiah or not: and others have been of opinion, as particularly Dr.
Lightfoot, that the reason of this message was, neither the ignorance and unbelief of John, or his disciples; but that John, with the rest of the Jews, having a notion of a temporal kingdom, and hearing of the mighty works of Christ, wonders that he himself was not delivered out of prison by him, grows impatient upon it, and asks, if he was the Messiah?
And if he was, why did he suffer his forerunner and chief minister to lie in prison?or do we look for another, to release me, and set up this kingdom?
