Acts 13:6-12

6 When they had gone through the whole island as far as Paphos, they met a certain magician, a Jewish false prophet, named Bar-Jesus.
7 He was with the proconsul, Sergius Paulus, an intelligent man, who summoned Barnabas and Saul and wanted to hear the word of God.
8 But the magician Elymas (for that is the translation of his name) opposed them and tried to turn the proconsul away from the faith.
9 But Saul, also known as Paul, filled with the Holy Spirit, looked intently at him
10 and said, "You son of the devil, you enemy of all righteousness, full of all deceit and villainy, will you not stop making crooked the straight paths of the Lord?
11 And now listen—the hand of the Lord is against you, and you will be blind for a while, unable to see the sun." Immediately mist and darkness came over him, and he went about groping for someone to lead him by the hand.
12 When the proconsul saw what had happened, he believed, for he was astonished at the teaching about the Lord.

13 Then Paul and his companions set sail from Paphos and came to Perga in Pamphylia. John, however, left them and returned to Jerusalem;
14 but they went on from Perga and came to Antioch in Pisidia. And on the sabbath day they went into the synagogue and sat down.
