'Chamber' in the Bible

And Ahaziah fell through the lattice in his upper chamber which was in Samaria, and became ill. So he sent messengers and said to them, “Go, inquire of Baal-zebub, the god of Ekron, whether I will recover from this sickness.”

Please, let us make a little walled upper chamber and let us set a bed for him there, and a table and a chair and a lampstand; and it shall be, when he comes to us, that he can turn in there.”

One day he came there and turned in to the upper chamber and rested.

He did away with the horses which the kings of Judah had given to the sun, at the entrance of the house of the Lord, by the chamber of Nathan-melech the official, which was in the precincts; and he burned the chariots of the sun with fire.

The altars 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 courts of the house of the Lord, the king broke down; and he smashed them there and threw their dust into the brook Kidron.
