'Upper' in the Bible

Ahaziah [the king of Israel] fell through the lattice (grid) in his upper chamber which was in Samaria, and became sick [from the injury]. So he sent messengers, saying to them, “Go, inquire of Baal-zebub, the god of Ekron, if I will recover from this sickness.”

So when Jehu came to Jezreel, Jezebel heard about it, and she painted her eyes and adorned her head and looked down from the [upper] window.

Only [the altars on] the high places were not removed; the people still sacrificed and burned incense on the high places [rather than in the temple]. He built the upper gate of the house of the Lord.

Then the king of Assyria sent the Tartan and the Rab-saris and the Rabshakeh [his highest officials] with a large army, from Lachish to King Hezekiah at Jerusalem. They went up and came to Jerusalem, and when they went up and arrived, they stood by the aqueduct of the upper pool, which is on the road of the Fuller’s Field.

The altars [dedicated to the starry host of heaven] which were on the roof, the upper chamber of Ahaz, which the kings of Judah had made, and the altars which Manasseh had made in the two courtyards of the house of the Lord, the king tore down; and he smashed them there and threw their dust into the Brook Kidron.
