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).

9736. And the staves shall be upon the two sides of the altar. That this signifies the power of good from which is truth, and of truth from good, is evident from the signification of “the staves,” as being power (as just above); and from the signification of “the two sides,” as being the good from which is truth, and truth from good; thus the marriage of good with truth and of truth with good. The reason of this is that the things which are on the right side in man bear relation to the good from which is truth, and the things which are on the left side bear relation to truth from good (see n. 9604); and that by the conjunction of these is therefore signified the marriage of good and truth (n. 9495 Wherefore the same things are signified by the sides of the altar, where were the staves; for all the representatives in nature bear relation to the human form, and have a signification according to their relation to this form (n. 9496).
