Passage 5.7.4
ὅσοι δὲ Ἑλλήνων ἢ Αἰγυπτίων ἐς Αἰθιοπίαν τὴν ὑπὲρ Συήνης καὶ ἐς Μερόην Αἰθιόπων πόλιν ἀναβεβήκασι, λέγουσιν οὗτοι τὸν Νεῖλον, ἐσιόντα ἐς λίμνην καὶ διʼ αὐτῆς διεξιόντα ὥσπερ ἐκ χέρσου, μετὰ τοῦτο ἤδη διʼ Αἰθιοπίας τῆς κάτω καὶ ἐς Αἴγυπτον ῥεύσαντα ἐπὶ Φάρον καὶ τὴν ταύτῃ θάλασσαν κατέρχεσθαι. ἐν δὲ τῇ γῇ ποταμὸν τῇ Ἑβραίων Ἰάρδανον καὶ αὐτὸς οἶδα λίμνην Τιβεριάδα ὀνομαζομένην διοδεύοντα, ἐς δὲ λίμνην ἑτέραν καλουμένην θάλασσαν Νεκράν, ἐς ταύτην ἐσιόντα καὶ ὑπὸ τῆς λίμνης αὐτὸν ἀναλούμενον.
As many Greeks or Egyptians as have ascended to Ethiopia beyond Syene, and to Meroë, the Ethiopian city, these say that the Nile, having entered a lake and having passed through it, as though traversing a dry land, afterwards flows through Lower Ethiopia and Egypt, and descends into the sea near Pharos and the waters around it. And I myself know in the land of the Hebrews a river called the Jordan, flowing through a lake named Tiberias, then entering another lake called the Dead Sea, where its waters are consumed in this lake.
