And when they agreed not among themselves, they departed, Paul speaking this one word: Well did the Holy Ghost speak to our fathers by Isaias the prophet,

“This is the Spirit that at the beginning "moved upon the thee of the waters; " by whom the world moves; by whom creation consists, and all things have life; who also wrought mightily in the prophets, and descended in flight upon Christ. This is the Spirit that was given to the apostles in the form of fiery tongues. This is the Spirit that David sought when he said, "Create in me a clean heart, O God, and renew a right spirit within me." Of this Spirit Gabriel also spoke to the Virgin, "The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee." By this Spirit Peter spake that blessed word, "Thou art the Christ, the Son of the living God." By this Spirit the rock of the Church was stablished. This is the Spirit, the Comforter, that is sent because of thee, that He may show thee to be the Son of God.”

“"Well said the Spirit:" as much as to say, It is not me that ye disbelieve. But God foreknew this from the first. "He discoursed," it says, "with boldness, unhindered": for it is possible to speak with boldness, yet hindered. His boldness nothing checked: but in fact he also spoke unhindered. "Well spake the Holy Ghost," etc. But this saying, "The Spirit said," is nothing wonderful: for an angel also is said to say what the Lord saith: but He the Spirit not so. When one is speaking of the things said by the angel, one does not say, Well said the angel, but, Well said the Lord. "Well said the Spirit:" as much as to say, It is not me that ye disbelieve. But God foreknew this from the first.”

“And when they agreed not among themselves,.... One part believing what was said, and the other disbelieving; and such a division is the usual effect of the Gospel ministry; see Luk 12:51. Or this may be understood of the unbelieving party, who though they agreed in the main that Jesus was not the Messiah, yet might have different sentiments of the apostle; of the manner of his reasoning, and the nature of his proofs and arguments; and of some things which he delivered, which some might assent to, and others deny; as the Pharisees and Sadducees in the sanhedrim at Jerusalem disagreed about the doctrine of the resurrection: and the rather this may be thought to be the sense, because they not only departed, when very likely those that believed might stay longer, but because at their departure the apostle says something very cutting and stinging, and which he would not say in common of them all, of the believers; and besides, they are afterwards said to reason among themselves, Act 28:29. They departed; from the apostle's lodging to their own houses, or to some other place, where they could call over, and debate among themselves, the things they had heard: after that Paul had spoken one word; a very remarkable one, and full to the purpose, and which he gave them just at parting with them: well spake the Holy Ghost by Esaias the prophet unto our fathers; the passage referred to is in Isa 6:9, which the prophet Isaiah delivered under the influence and by the inspiration of the Holy Ghost, being moved by him, as all the holy men of God were; and which was very appropriate, not only to the Jewish fathers in the times of Isaiah, but to their posterity in succeeding ages, in the times of Christ and his apostles; see Mat 13:10; and were exceeding applicable to the present unbelieving Jews, who had been disputing with the apostle, and were now departing from him, in unbelief: and from hence it appears, that since it was the Holy Ghost that spake by Isaiah the prophet, and he that spoke to him and by him, was the Adon, Jehovah, and Lord of hosts, as is clear from Isa 6:1; it follows, that the Holy Ghost is a divine person, truly God, and equal with the Father and the Son.”

“when they--the Jews. agreed not among themselves--the discussion having passed into one between the two parties into which the visitors were now divided, respecting the arguments and conclusions of the apostle. they departed--the material of discussion being felt by both parties to be exhausted. after Paul had spoken one word--one solemn parting testimony, from those Scriptures regarded by both alike as "the Holy Ghost speaking" to Israel.”
