The second room was called the Most Holy Place. It was approximately 10 x 10 x
10 cubits (15 x 15 x 15 feet).
This was the very place where God spoke to Moses from off the blood-stained Mercy Seat of
the Ark of the Covenant
Once a year the High Priest entered on the
Day of Atonement
and met God amidst the smoke of burning incense
Inside the Most Holy Place, there was no other light source except the light coming from the
glory of God shone from the Mercy Seat.
