Zaphnath-paaneah
Which in Coptic signifies a revealer of secrets, or, the man to whom secrets are revealed. Jerome says this name signified in Egyptian, {Savatorem mundi,} "the Saviour of the world;" and {Psotem-phaneh,} in Coptic, is certainly "salvation of the world," from [SOT,] for [soteria ,] salvation, {em,} the sign of the genitive case, and [PHENEH], world. If this interpretation be correct, Pharaoh must have meant Egypt by the world, or which Joseph might be justly termed the Saviour. We know that the Romans called their empire {Universis Orbis-Orbis Terrarum,} "all the world:" the Chinese say the same of their empire at the present day, and the phrase is used in the East: Nadir Shah is described on his coins as "Conqueror of the World," i.e., Persia. See the same phraseology applied to Syria, Palestine, etc.
