38However, Paul told Barnabas that he thought that it would not be good to take Mark with them, because Mark had deserted them when they were previously in Pamphylia region, and had not continued to work with them.
39Paul and Barnabas strongly disagreed with each other about that, so they separated. Barnabas took Mark along with him and they got on a ship and went to Cyprus.
