But when the apostles ¹  Barnabas and Paul heard about ²  it, they tore ³  their clothes and rushed out ⁴  into the crowd, shouting, ⁵ 

So Joseph, a Levite who was a native of Cyprus, called by the apostles Barnabas (which is translated “son of encouragement”), ¹ 

But Paul and Barnabas remained in Antioch, ¹  teaching and proclaiming (along with many others) ²  the word of the Lord. ³ 

But Barnabas took ¹  Saul, ²  brought ³  him to the apostles, and related to them how he had seen the Lord on the road, that ⁴  the Lord had spoken to him, and how in Damascus he had spoken out boldly ⁵  in the name of Jesus.

Now there were these prophets and teachers in the church at Antioch: ¹  Barnabas, Simeon called Niger, ²  Lucius the Cyrenian, ³  Manaen (a close friend of Herod ⁴  the tetrarch ⁵  from childhood ⁶ ) and Saul.

Both Paul and Barnabas replied courageously, ¹  “It was necessary to speak the word of God ²  to you first. Since you reject it and do not consider yourselves worthy ³  of eternal life, we ⁴  are turning to the Gentiles. ⁵
