All the multitude held their peace. By these words, Luke giveth us to understand that the Spirit of God did so reign in that assembly, that they yielded forthwith to reason. The disputation was hot before; but now, after that Peter hath laid open the counsel of God, and hath handled the question according to the doctrine of the Scripture, by and by all noise being stayed, they are quiet and whist who did of late unadvisedly defend the error. This is a lively image of a lawful Council, when the truth of God alone, so soon as it is once come to light, maketh an end of all controversies; and assuredly it is effectual enough to appease all discord when the Spirit beareth the chief sway; because he is again a fit governor, as well to moderate their tongues who must speak before others as to keep the rest under obedience, that they be not too much addicted to themselves and wedded to their own wills, but that, laying away stubbornness, they may show themselves obedient to God. Neither is it to be doubted but that there was some few which would not yield, as it falleth out in a great assembly; yet the truth of God had the upper hand, so that the silence whereof Luke speaketh was a manifest testimony of common obedience. And this was no small moderation in Peter, in that having suffered every one to say for himself what he could, he deferred his judgment (lest it should be prejudicial to others) so long, until the question had been thoroughly discussed to and fro. They heard Barnabas and Paul. We may gather by these words that they were not heard with silence before.: For seeing that the more part was persuaded that they did wickedly admit the profane Gentiles into the Church, there should nothing which they should have said have been patiently received until this false opinion were corrected and reformed; but all should have been taken at the worst. We see what a poison displeasure conceived for no cause is, which doth so possess men's minds, that it stoppeth the way, so that the truth can never have en, trance. Hereby we learn how true that saying is, All things are sound to the sound, (Titus 1:15,) for there is nothing so wholesome but corrupt affection do turn the same into that which is hurtful. And to this end tendeth the narration made by Paul and Barnabas, that they may show and prove that God doth allow their apostleship among the Gentiles; forasmuch as it was ratified and confirmed by miracles, which are, as it were, certain seals thereof.

Then all the multitude - Evidently the multitude of private Christians who were assembled on this occasion. That it does not refer to a synod of ministers and elders merely is apparent:
(1) Because the church, the brethren, are represented as having been present, and as concurring in the final opinion Acts 15:22-23; and,
(2) Because the word "multitude" τὸ πλῆθος to plēthos would not have been used in describing the collection of apostles and elders merely. Compare Luke 1:10-11, Luke 1:13; Luke 5:6; Luke 6:17; Luke 19:37; John 5:3; John 21:6; Acts 4:32; Acts 6:2; Matthew 3:7.
Gave audience - Heard, listened attentively to.
Barnabas and Paul - They were deeply interested in it, and they were qualified to give a fair statement of the facts as they had occurred.
Declaring what miracles and wonders - The argument here evidently is, that God had approved their work by miracles; that he gave evidence that what they did had his approbation; and that as all this was done without imposing on them the rites of the Jews, so it would follow that those were not now to be commanded.

All the multitude kept silence - The strong facts stated by St. Peter could not be controverted. His speech may be thus analyzed:
1. Circumcision is a sign of the purification of the heart.
2. That purification can only be effected by the Holy Ghost.
3. This Holy Spirit was hitherto supposed to be the portion of those only who had received circumcision.
4. But the Gentiles, who were never circumcised, nor kept any part of the law of Moses, have had their hearts purified by faith in Christ Jesus.
5. As God, therefore, has given them the thing signified, he evidently does not intend that the sign should be administered.
6. Should we impose this burthensome rite, we should most evidently be provoking God, who plainly shows us that he intends no more to save in this way.
7. Therefore it is evident that both Jews and Gentiles are to be saved through the grace of the Lord Jesus Christ.
Gave audience to Barnabas and Paul - These apostles came forward next, to corroborate what Peter had said, by showing the miracles and wonders which God had by them wrought among the Gentiles. Peter stated facts: Paul and Barnabas confirmed the statement.

(6) Then all the multitude kept silence, and gave audience to Barnabas and Paul, declaring what miracles and wonders God had wrought among the Gentiles by them.
(6) A true pattern of a lawful council, where God's truth alone reigns.

Then all the multitude kept silence,.... Upon this oration of Peter's, there was a profound silence in the whole assembly, among all the brethren of the church, who were come together on this occasion; they were all satisfied with, and by their silence acquiesced in, what Peter said; and waited to hear what might be further said about this matter, by other persons in the assembly; and even those who were on the other side of the question, were confounded and nonplussed, and knew not what to say, and the more so, when they perceived that the rest of the apostles and elders were of the same mind; for Beza's most ancient copy introduces this clause thus; "then the elders agreeing to the things that were said by Peter, the whole multitude was silent": and this gave Paul and Barnabas an opportunity of being heard; who, perhaps, could not so well be heard before, for the clamour of the people against them, who might not have so good an opinion of them, and of their practices:
and gave audience to Barnabas and Paul; Barnabas is mentioned first, he being most known to the Jews, and of whom they might have the better opinion; and who probably gave the account of their proceedings and success among the Gentiles:
declaring what miracles and wonders God had wrought among the Gentiles by them; what wonders of grace were wrought in the conversion of multitudes of them, wherever they came; and what miracles in nature were wrought for the confirmation of the Gospel, such as the striking blind Elymas the sorcerer, at Paphos in Cyprus, and curing the cripple at Lystra; and which they ascribe not to themselves but to God, whose instruments they only were.

Then all . . . gave audience to Barnabas and Paul--On this order of the names here, see on Acts 15:25.
declaring what miracles and signs God wrought among the Gentiles by them--This detail of facts, immediately following up those which Peter had recalled to mind, would lead all who waited only for divine teaching to see that God had Himself pronounced the Gentile converts to be disciples in as full standing as the Jews, without circumcision; and the attesting miracles to which Paul here refers would tend, in such an assembly to silence opposition.

All the multitude kept silence. After Peter's reminder of his work among the Gentiles, Paul and Barnabas were probably called on to show whether their work, like Peter's, showed that God was with them. They therefore gave some account of the miracles that God had wrought by their hands, thereby attesting the Divine favor.

Miracles and wonders - By which also what St. Peter had said was confirmed.
