Acts 11:24

πλήρης πνεύματος ἁγίου καὶ πίστεως, full of the Holy Ghost and faith. The same description is given of Stephen (Acts 6:5), and a man of like character with that most eminent among the Greek-Jews would exert much influence in Antioch, where Greeks and Greek-Jews were the chief part of the population. It was in consequence of the persecution after Stephen’s death that these preachers had come to Antioch, and some of them were probably of those Grecians who had been forward in the work for which Stephen was martyred.

καὶ προσετέθη ὄχλος ἱκανός, and much people was added. No doubt the joyful approval of Barnabas, representing the Mother-Church of Jerusalem, would help forward the zeal of the preachers at Antioch.
