'Chamber' in the Bible

Guard and look after [them] until you weigh [them] before the chief priests, the Levites, and the heads of the {families} of Israel in Jerusalem, in the chamber of the house of Yahweh."

Ezra rose from before the house of God and went to the chamber of Jehohanan son of Eliashib. He did not eat food nor drink water because he was mourning over the sin of the exiles.
