The Holy of Holies
This room was divided, in two, by a large heavy tapestry on which the images of the cherubim were embroidered. The room created behind the veil represents what is in heaven. This room was called the Holy of Holies and was the holiest place in the Tabernacle where the Ark of the Covenant rested. It's lid the Mercy Seat a depiction of the description of Genesis 3:24. "...and placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life."
