William Burkitt on Acts 15:32

Judas and Silas being prophets; that is, persons extraordinarily inspired, and endued with eminent gifts for teaching and interpreting the holy scriptures; they employed themselves at Antioch, confirming and building up their brethren in the faith of Christ. And after they had stayed at Antioch some time, they were with all kindness dismissed of the church there; and Judas returned to Jerusalem, to acquaint the apostles with the reception which their letter had met with, and what obedience was readily given to their decrees.
