Pa'u (Heb. Pau', פָּעוּ, a bleating, or yawning; but in 1Ch 1:50, PAI, פָּעַי, though some copies agree with the reading in Genesis; Sept. Φογώρ, i.e. chasm; Vulg. Phau), the capital of Hadar, king of Edom (Ge 36:39). The only name that bears any resemblance to it is Phauara, a ruined place in Idumaea mentioned by Seetzen.
