PATROBAS

pat'-ro-bas (Patrobas): The name of a member of the Christian community at Rome to whom Paul sent greetings (Romans 16:14). The name is an abbreviated form of "Patrobius." There was a wealthy freedman of Nero of the same name who was put to death by Galba (Tacitus, History i.49; ii.95). The Patrobas of Paul may have been a dependent of his.
