9686. And thou shalt make a covering for the door of the Tent. That this signifies the intermediate that unites the second or middle heaven with the first or ultimate heaven, is evident from the signification of the "covering," as being the intermediate that unites this heaven, which is represented by the Tent of meeting, with the heaven represented by the court, which is treated of in the following chapter. For as "the veil" between the holy and the holy of holies signified the uniting intermediate between the inmost or third heaven and the middle or second heaven, so this "covering" signifies the like between the middle or second heaven and the first or ultimate heaven. That there are three heavens, and that two of them were represented by the Habitation that was inside the veil and the Habitation that was outside the veil, has been shown above; and that the first or ultimate heaven is represented by the court, will of the Lord's Divine mercy be shown in the following chapter. The entrance from the one heaven into the other is signified by "the door" where the covering was. That a "door" signifies entrance, see n. 2145, 2152, 2356, 2385; and hence communication (n. 8989); wherefore "the covering" at the entrance, which was in the place of a door, denotes the intermediate that communicates and unites.
