'Upstairs' in the Bible

Then Ehud approached him while he was sitting alone in his room upstairs where it was cool. Ehud said, “I have a word from God for you,” and the king stood up from his throne.

Ehud escaped by way of the porch, closing and locking the doors of the upstairs room behind him.

Ehud was gone when Eglon’s servants came in. They looked and found the doors of the upstairs room locked and thought he was relieving himself in the cool room.

The servants waited until they became worried and saw that he had still not opened the doors of the upstairs room. So they took the key and opened the doors—and there was their lord lying dead on the floor!
