"For He founded it upon the seas, and established it upon the rivers. This refers to the Land of Israel, which rests upon seven seas: the Great Sea, the Sea of Tiberias, the Sea of Sodom, the Sea of Sivkhin, the Sea of Chultha, the Sea of the Arabah, and the Sea of Aspamia. And the Land of Israel is situated in the heat of the sun. The Holy One, blessed be He, restrains the rivers, and makes them flow, as it is written: 'He established it upon the rivers'. The Jordan, the Pishon, the Gihon, and the Euphrates all flow out from Eden. And it is written, 'and it is seen upon the face of the desert' (Numbers 21:20). Rabbi Abba bar Ḥiyya said, 'Whoever ascends to Mount Nebo sees a likeness of a ship in the Sea of Tiberias, and it is the well of Miriam'."
