'Upper Room' in the Bible

Then Ehud went out into the vestibule and shut the doors of the upper chamber behind him, and locked them.

When Ehud departed, Eglon’s servants came. And when they saw that the doors of the upper room were locked, they said, “He is only relieving himself in the cool room.”

They waited [a very long time] until they became embarrassed and uneasy, but he still did not open the doors of the upper room. So [finally] they took the key and opened them, and behold, their master had fallen to the floor, dead.

After him Malchijah, one of the goldsmiths, carried out repairs as far as the house of the temple servants and of the merchants, in front of the Inspection Gate and as far as the upper room of the corner.

Between the upper room of the corner and the Sheep Gate the goldsmiths and merchants carried out repairs.

Who lays the beams of His upper chambers in the waters [above the firmament],Who makes the clouds His chariot,Who walks on the wings of the wind,

He waters the mountains from His upper chambers;The earth is satisfied with the fruit of His works.
