One of the Twelve Apostles, mentioned sixth in the three Gospel lists (Matthew 10:3; Mark 3:18; Luke 6:14), and seventh in the list of Acts (1:13).
The name (Bartholomaios) means "son of Talmai" (or Tholmai) which was an ancient Hebrew name, borne, e.g. by the King of Gessur whose daughter was a wife of David (2 Samuel 3:3). It shows, at least, that Bartholomew was of Hebrew descent; it may have been his genuine proper name or simply added to distinguish him as the son of Talmai. Outside the instances referred to, no other mention of the name occurs in the New Testament.
