'Upper chambers' in the Bible

Then David gave to his son Solomon the plan for the porch of the temple, its buildings, its treasuries, its upper chambers, its inner rooms, and for the place for the [ark and its] mercy seat;

The weight of the nails was fifty shekels of gold. He also overlaid the upper rooms with gold.

“Woe (judgment is coming) to him who builds his house by [acts of] unrighteousnessAnd his upper chambers by injustice,Who uses his neighbor’s service without payAnd does not give him wages [for his work],

Now the upper chambers were smaller because the galleries took away more space from them than from the chambers on the lower and middle stories of the building;

for they were in three stories and did not have pillars like the pillars of the [outer] courtyards; therefore the upper chambers were set back from the ground more than the lower and the middle ones.

It is He who builds His upper chambers in the heavensAnd has established His vaulted dome (the firmament of heaven) over the earth,He who calls to the waters of the seaAnd pours them out on the face of the earth—The Lord is His name.
