What did the Shekinah glory represent in the tabernacle?
The Shekinah glory represented the holy God's presence in the tabernacle. It appeared as the cloud by day and fire by night above the Ark of the Covenant behind the veil, showing that the holy God dwelt there and that access to Him was restricted.
Les explains that the veil depicted the very body of Christ Himself, because it kept even the priests from any approach to the Holy God, who was represented by the Shekinah glory—the cloud by day and fire by night. If the tabernacle could be lifted to a plane, that cloud would be directly above the Ark of the Covenant. The heavy curtain kept anyone from approaching except the high priest once a year, as Leviticus 16 shows.
