Acts 9:29

But Barnabas took him, and brought him to the apostles, and declared unto them how he had seen the Lord in the way, and that he had spoken to him, and how he had preached boldly at Damascus in the name of Jesus.

And he was with them coming in and going out at Jerusalem.

Which when the brethren knew, they brought him down to Caesarea, and sent him forth to Tarsus.

Then had the churches rest throughout all Judaea and Galilee and Samaria, and were edified; and walking in the fear of the Lord, and in the comfort of the Holy Ghost, were multiplied.
