'Upper Room' in the Bible

Ahaziah had fallen through the lattice in his upper room, which [was] in Samaria, and he was injured. So he sent messengers, and he said to them, "Go, inquire of Baal-Zebub, the god of Ekron, if I will survive this injury."

One day it happened that he came there and went to the upper room and lay down there.

The altars which [were] on the roof of the upper room of Ahaz, which the kings of Judah had made, and the altars which Manasseh had made in the two courtyards of the temple of Yahweh, the king tore down and ran from there and threw their ashes into the Wadi Kidron.
