Devarim 1:7

Turn you, and take your journey, and go to the Har HaEmori (hill country of the Amorites), and unto all the places nigh thereunto, in the Aravah, in the hills, in the Shefelah, and in the Negev, and by the seacoast, to the Eretz HaKena'ani (Land of the Canaanites), and unto Levanon, unto the great river, the river Euphrates.
