'Hill country' in the Bible

Upon descending from the hill country He was followed by immense crowds.

Not long after this, Mary rose up and went in haste into the hill country to a town in Judah.

And all who lived round about them were filled with awe, and throughout the hill country of Judaea reports of all these things were spread abroad.

About that time He went out on one occasion into the hill country to pray; and He remained all night in prayer to God.
