Numbers 13:17

Southward - Rather, “by the Negeb,” or south-country; a well-defined tract of territory forming the southernmost and least fertile portion of the land of Canaan and of the subsequent inheritance of Judah. It extended northward from Kadesh to within a few miles of Hebron, and from the Dead Sea westward to the Mediterranean (see especially Joshua 15:21).

Into the mountain - The hill-country of southern and central Canaan, mostly within the borders of Judah and Ephraim. It commences a few miles south of Hebron, and extending northward to the plain of Jezreel, runs out eventually northwest-ward into the sea in the headland of Carmel.
