 Kenneth Kitchen and James Hoffmeier state that these reedy lakes and marshes along the isthmus of Suez are acceptable locations for "yam suf".The ancient "yam suf" is not confined to the modern Red Sea.Hoffmeier equates "yam suf" with the Egyptian term "pa-tjufy" (also written "p3 twfy") from the Ramsside period, which refers to lakes in the eastern Nile delta.
