GEGHON (Hebrew Gîhôn). — The second of the four rivers into which the stream divides at its exit from Eden; it flows through the entire land of KUSH (Gen 2:10, 13).
Given the mention of the Tigris and Euphrates (cf. V. 14; cf. PARADISE, EARTHLY), G. is probably the ancient Araxes, now called Aras, which the Arabs call Gajhūn er-Rās, whose sources are near those of the Tigris and Euphrates and which empties into the Caspian Sea; and KUSH the region (Kāšū) to the east of Mesopotamia (Gen 10:8), whose name would be preserved in the first dynasty after the flood, in the city of KISH and perhaps also in the name of the Kossaeans who ruled Babylon in the second millennium.
