John Gill

And after they had held their peace,.... Meaning not the multitude, but Paul and Barnabas; when they had finished their account, and had done speaking: James answered; or rose up, as the Syriac version reads, he stood up and began to speak. This was James the son of Alphaeus, one of the twelve apostles, sometimes called the brother of the Lord; for the other James, the son of Zebedee and brother of John, was dead, being killed by Herod, Act 12:2 but this was the brother of Jude, and the same that wrote the epistle that bears his name: whether he was now bishop or pastor of the church at Jerusalem, is not certain; nor whether he was president in this council; the speeches made in it do not appear to be directed to him: he began his oration thus, saying, men and brethren, hearken to me; the titles he uses, and the manner of desiring audience, were what were common with the Jews; see Act 2:14.
