'Chamber' 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.”

Please, let us make a small, fully-walled upper room [on the housetop] and put a bed there for him, with a table, a chair, and a lampstand. Then whenever he comes to visit us, he can turn in there.”

One day he came there and turned in to the upper room and lay down to rest.

When you arrive there, look for Jehu the son of Jehoshaphat the son of Nimshi, and go in and have him arise from among his brothers, and take him into an inner room.

And he got rid of the horses that the kings of Judah had given [in worship] to the sun at the entrance of the house of the Lord, by the chamber of Nathan-melech the official, which was in the annex; and he burned the chariots of the sun.

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.
