The Acts 13:1-3

Now there were at Antioch, in the church that was there, prophets and teachers, Barnabas, and Symeon that was called Niger, and Lucius of Cyrene, and Manaen the foster-brother of Herod the tetrarch, and Saul. And as they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them. Then, when they had fasted and prayed and laid their hands on them, they sent them away.
