'Chamber' in the Bible

The lowest chamber was 7½ feet wide, the middle was nine feet wide, and the third was 10½ feet wide. He also provided offset ledges for the temple all around the outside so that nothing would be inserted into the temple walls.

The door for the lowest side chamber was on the right side of the temple. They went up a stairway to the middle chamber, and from the middle to the third.

Micaiah replied, “You will soon see when you go to hide yourself in an inner chamber on that day.”
