'Hill country' in the Bible

And Moses sent them to search out the land of Canaan, and said to them, Go up this way by the south and go up into the hill-country,

Amalek dwells in the land of the south; and the Hittites, and the Jebusites, and the Amorites dwell in the hill-country; and the Canaanites dwell by the sea, and by the side of the Jordan.

They got up early the next morning and went up the ridge of the hill country, saying, “Let’s go to the place the Lord promised, for we were wrong.”

But they dared to go up the ridge of the hill country, even though the ark of the Lord’s covenant and Moses did not leave the camp.

Then the Amalekites came down, and the Canaanites who dwelt in that hill country, and struck them, and routed them, even unto Hormah.
