Acts 15:37-39

Common(i) 37 Barnabas wanted to take John, also called Mark, with them. 38 But Paul kept insisting that they should not take along one who had deserted them in Pamphylia, and had not gone with them to the work. 39 There arose such a sharp disagreement that they separated from one another, and Barnabas took Mark with him and sailed away to Cyprus.
