Holy of holies
Easton, 1897
The second or interior portion of the tabernacle. It was left in total darkness. No one was permitted to enter it except the high priest, and that only once a year. It contained the ark of the covenant only (Exodus 25:10-16). It was in the form of a perfect cube of 20 cubits. (See TABERNACLE.)
