9861. Foursquare it shall be, doubled. That this signifies what is righteous and perfect, is evident from the signification of “foursquare,” as being what is righteous (see n. 9717). That it also means what is perfect, is because it was doubled, and that which is doubled involves all things of good and all things of truth. That which is on the right side involves the good from which is truth, and that which is on the left side involves the truth which is from good (n. 9495, 9604, 9736), thus the perfect conjunction of both is involved. It is also from this that “two” signifies conjunction (n. 8423), and also each and all things (n. 9166), as likewise what is full (n. 9103).

9604. Five curtains shall be joined together one to the other; and five curtains shall be joined together one to the other. That this signifies the constant communication of truth with good, and of good with truth, is evident from the signification of “five,” as being all things of one side, for by “ten” are signified all things of the whole (see n. 9595); and from the signification of the “curtains,” as being the interior truths of faith, which are of the new understanding (see also n. 9595). Hence, as five of the ten curtains were joined together, and also the other five, they therefore signified the reciprocal communication of truth and good, and of good and truth; for the communications must be reciprocal in order that there may be a conjugial conjunction of truth and good. The like things are signified by these curtains as by the things that belong to the left side and the right side in man. Those which belong to his right side relate to the good from which is truth, but those of the left side relate to the truth which is from good; and in the middle of these there is the communication of good with truth, and of truth with good, from which there results a perpetual and constant conjunction. Such are the things signified by the words, “five curtains shall be joined together one to the other, and five curtains shall be joined together one to the other.”
