'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."

Then Ezra rose up from before the house of God, and went into the chamber of Johanan the son of Eliashib: and when he came thither, he did eat no bread, nor drink water: for he mourned because of the transgression of them that had been carried away.
