'Chamber' in the Bible

Ehud approached him while he was sitting by himself in the cool roof chamber of his palace. He said, "I have a message from God for you!" So when Eglon got up from his seat,

Then Ehud left the cool chamber in the direction of the vestibule, shutting and locking the doors behind him.

After he left, Eglon's attendants came to look, but the doors to the cool chamber were locked! So they said, "He must be relieving himself in the inner part of the cool chamber."

They waited until they were embarrassed, since he never opened the doors to the chamber. Eventually they took a key, opened the doors, and found their master dead on the ground.

When all the "lords" at the tower of Shechem heard what had happened, they retreated into the inner chamber of the temple of El-berith.

Then his entire army also cut down a branch for each soldier, followed Abimelech to the inner chamber, and set fire to it while they were inside. As a result, all the men of the tower of Shechem died, including about a thousand men and women.
