"And Judas and Silas, being prophets also themselves, exhorted the brethren with many words, and confirmed them. And after they had tarried there a space, they were let go in peace from the brethren unto the Apostles." No more factions and fightings, but thenceforth Paul taught. After the epistle, then Judas and Silas also themselves exhort them by word: for this also was needful, that Paul and Barnabas might be quit of all suspicion. "Being prophets also themselves," it says, exhorted the brethren "with many words." It shows here the right that Paul and Barnabas have to be believed. For Paul also might have done this, but it behooved to be done by these.
They were dismissed in peace by the brethren to those who had sent them. Where it is written To those who had sent them, in the Greek it is written To the Apostles.
[AD 407] John Chrysostom on Acts 15:32-33
