'Inner chamber' in the Bible

When all the leaders of the tower of Shechem heard of it, they entered the inner chamber of the temple of El-berith.

All the people also cut down each one his branch and followed Abimelech, and put them on the inner chamber and set the inner chamber on fire over those inside, so that all the men of the tower of Shechem also died, about a thousand men and women.

But the rest fled to Aphek into the city, and the wall fell on 27,000 men who were left. And Ben-hadad fled and came into the city into an inner chamber.
