'Upper' in the Bible

He built Upper Beth-horon and Lower Beth-horon—fortified cities with walls, gates, and bars—

Then he took with him the commanders of hundreds, the nobles, the governors of the people, and all the people of the land and brought the king down from the Lord’s temple. They entered the king’s palace through the Upper Gate and seated the king on the throne of the kingdom.

Jotham built the Upper Gate of the Lord’s temple, and he built extensively on the wall of Ophel.

This same Hezekiah blocked the outlet of the water of the Upper Gihon and channeled it smoothly downward and westward to the city of David. Hezekiah succeeded in everything he did.
