'Upper chambers' in the Bible

Then David gave to Solomon his son the pattern of the porch, and of the houses thereof, and of the treasuries thereof, and of the upper chambers thereof, and of the inner parlours thereof, and of the place of the mercy seat,

And the weight of the nails was fifty shekels of gold. And he overlaid the upper chambers with gold.

Now the upper chambers were shorter: for the galleries were higher than these, than the lower, and than the middlemost of the building.
