Acts 15:37-41

Barnabas wanted to take John along, the John nicknamed Mark. But Paul wouldn’t have him; he wasn’t about to take along a quitter who, as soon as the going got tough, had jumped ship on them in Pamphylia. Tempers flared, and they ended up going their separate ways: Barnabas took Mark and sailed for Cyprus; Paul chose Silas and, offered up by their friends to the grace of the Master, went to Syria and Cilicia to put grit in those congregations.
