Acts 15:36-39

36 After some time, Sha'ul said to Bar-Nabba, "Let's go back and visit the brothers in all the towns where we proclaimed the message about the Lord, and see how they're doing."

37 Now Bar-Nabba wanted to take with them Yochanan, the one called Mark.

38 But Sha'ul thought it would be unwise to take this man with them, since he had gone off and left them in Pamphylia to do the work by themselves.

39 There was such sharp disagreement over this that they separated from each other, with Bar-Nabba taking Mark and sailing off to Cyprus.
