Acts 15:33-37

³³After Judas and Silas had stayed in Antioch for some time and were ready to return to Jerusalem , the believers there wished them well, and the believers prayed that God would protect them as they traveled. So the two men started to go back to the leaders in Jerusalem who had asked them to go to Antioch .

³⁵However, Paul and Barnabas continued to stay in Antioch. While they were there, they, along with many others, were teaching people and preaching to them the message about the Lord Jesus.

³⁶After some time Paul said to Barnabas, “Let's go back and visit the fellow believers in every city where we previously proclaimed the message about the Lord Jesus. In that way, we will know how well they are continuing to believe in the Lord Jesus.”

³⁷Barnabas agreed with Paul, and said that he wanted to take John, whose other name was Mark, along with them again.
