Obe was the name of a male Ferengi of legend.
Obe was an honest shopkeeper in the village of Noi, who sold high-quality goods at fair prices. When Obe was overpaid for a can of beetle snuff by a customer named Greb from the village of Korpa, he set out to pay the man back. Obe was killed on the road to Korpa by assassins hired by Greb, who then moved into Obe's house, took over his business, and married his widow. The story of Obe is used as an illustration of the First Rule of Acquisition. (DS9 reference: Legends of the Ferengi)
