'Hill country' in the Bible

And Moses sent them to spy out the land of Canaan, and said to them, Get you up this way by the South, and go up into the hill-country.

Amalek dwells in the land of the South. And the Hittite, and the Jebusite, and the Amorite, dwell in the hill-country. And the Canaanite dwells by the sea, and along by the side of the Jordan.
