Acts 15:12

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.
