25 And Barnabas and Saul returned from Jerusalem when they had completed their service, bringing with them John, whose other name was Mark.
Barnabas and Saul Sent Off
13:1 Now there were in the church at Antioch prophets and teachers, Barnabas, Simeon who was called Niger, Lucius of Cyrene, Manaen a member of the court of Herod the tetrarch, and Saul. 2 While they were worshiping the Lord and fasting, the Holy Spirit said, “Set apart for me Barnabas and Saul for the work to which I have called them.” 3 Then after fasting and praying they laid their hands on them and sent them off.
21 When they had preached the gospel to that city and had made many disciples, they returned to Lystra and to Iconium and to Antioch, 22 strengthening the souls of the disciples, encouraging them to continue in the faith, and saying that through many tribulations we must enter the kingdom of God. 23 And when they had appointed elders for them in every church, with prayer and fasting they committed them to the Lord in whom they had believed.
