hill (country), mount(-ain), X promotion

Concise Bible Dictionary:

The ordinary word for this is har, which is employed both for the mountain ranges, some of which run through Israel from north to south, and also for the higher mountains that rise upon those ranges or on the plains. Thus in 2 Chronicles 13:4 it says, “Mount Zemaraim, which is in mount Ephraim,” which means that mount Zemaraim was situated in the hill-country of Ephraim. Mount Ephraim does not refer to any particular mountain; but to the range of hills, or hill country in Ephraim, extending from Bethel to the plains of Jezreel. In like manner there are parts that can be called hill-country throughout all the land, as in Joshua 13:6 and Luke 1:39,65. Each of the mountains is considered under its own name.
