'Upper' in the Bible

The weight of the nails was fifty shekels of gold. He overlaid the upper rooms with gold.

Also he built Beth Horon the upper, and Beth Horon the lower, fortified cities, with walls, gates, and bars;

He took the captains of hundreds, and the nobles, and the governors of the people, and all the people of the land, and brought down the king from the house of Yahweh: and they came through the upper gate to the king's house, and set the king on the throne of the kingdom.

He built the upper gate of the house of Yahweh, and on the wall of Ophel he built much.

This same Hezekiah also stopped the upper spring of the waters of Gihon, and brought them straight down on the west side of the city of David. Hezekiah prospered in all his works.
