this is impossible, since, as we have seen above, Gen. 2:13 states that the Gihon ‘flows around the whole land of Kush’, that is, Nubia. Although having faulty geographical knowledge, the Israelites were fully aware that Jerusalem did not link up with the Tigris and Euphrates, anymore than it linked up with the likely identification of the Pishon noted above. Nevertheless, the name Gihon coheres with a number of other pieces of evidence indicating that Zion could be conceived in paradisiacal terms.
