'Chamber' in the Bible

And when the king entered into the house of the LORD, the guard came and fetched them, and brought them again into the guard chamber.

And Micaiah said, Behold, thou shalt see on that day when thou shalt go into an inner chamber to hide thyself.

The Levites shall surround the [young] king, every man with his weapons in his hand; and whoever comes into the temple [breaking through the ranks of the guard to get near Joash] is to be killed. You are to be with the king when he comes in [from the temple chamber where he is hiding] and when he goes out.”
