Greek form of an Aramaic name. In Acts in the New Testament the byname Barnabas was given to a man named
Joseph, a Jew from Cyprus who was a companion of
Paul on his missionary journeys. The original Aramaic form is unattested, but it may be from
בּר נביא (bar naviya') meaning "son of the prophet", though in Acts 4:36 it is claimed that the name means "son of encouragement". As an English name, it came into occasional use after the 12th century.
