'Country' in the Bible

Later, the army of Judah left Jerusalem to attack the Canaanites who lived in the hill country, the Negev, and the Shephelah.

The LORD was with the army of Judah, and they captured the hill country, but did not expel the inhabitants of the valley because they were equipped with iron chariots.

Later on, the Amorites forced the descendants of Dan into the hill country and did not permit them to come into the valleys of the hills.

The LORD God of Israel handed Sihon and his entire army into the control of Israel, and defeated them. As a result, Israel took control over the entire land of the Amorites, who were living in that country.
