'Inner chamber' in the Bible

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.
