2524. And she herself also said, He is my brother. That this signifies that the rational itself dictated that celestial good should be adjoined to it, is evident from the signification of a “sister” (here meant by “she herself”) as being the rational (n. 1495, 2508); and from the signification of a “brother,” as being the good of truth (n. 367, 2508). For the case herein is as follows: Divine good and Divine truth are united to each other as if by marriage; for thence comes the heavenly marriage, and thence comes marriage love also, even down to lower nature. But the good and truth of the rational are not conjoined with each other as by marriage, but by consanguinity, like brother and sister; since the rational as to truth is conceived from the influx of Divine good into the affection of knowledges [scientiarum et cognitionum] (see n. 1895, 1902, 1910); and the good of the rational, through the influx of Divine good into that truth, which then becomes the good itself of charity, which is the “brother” of faith, or what is the same, of truth (n. 367)

[2] But in regard to the good and truth of the rational, the procuring of this takes place in such a way that its good is from Divine good, whereas its truth is not from Divine truth; for the truth of the rational is procured by means of knowledges [scientias et cognitiones], which are insinuated through the external and internal senses, thus by an external way. Hence it is that there adhere to its truths many fallacies from the senses, which cause the truths not to be truths; nevertheless when Divine good flows into them, and conceives them, they then appear as truths, and are acknowledged as truths, although they are nothing but appearances of truth. The good itself is then modified in these truths according to the shades there, and becomes in quality like the truth. This is one arcanum which lies hidden in these words, that the rational thus dictated that celestial good should be adjoined to it.

2508. She is my sister. That this signifies rational truth, is evident from the signification of a “sister,” as being rational intellectual truth (see n. 1495). That rational truth is a “sister,” can be seen only from the heavenly marriage; for the things which descend from this have kinships among themselves like the relationships and connections on earth (concerning which see n. 685, 917); and this with indefinite variety. The heavenly marriage itself exists solely between the Divine good and the Divine truth. From this there are conceived in man the intellectual, the rational, and the faculty of knowing; for without conception from the heavenly marriage man cannot possibly be imbued with understanding, with reason, or with knowledge, and consequently cannot be man. In proportion therefore as he receives from the heavenly marriage, in the same proportion is he man. The heavenly marriage is in the Lord Himself, thus the Lord is this marriage itself, for He is the Divine good itself and at the same time the Divine truth. Angels and men are in the heavenly marriage insofar as they are in love to the Lord and in charity toward the neighbor, and insofar as they are thence in faith; that is, insofar as they are in the Lord’s good, and thence in truth; and they are then called “daughters and sons,” and in their relation to one another “sisters and brothers;” but this with differences. The reason why rational truth is called a “sister” is that it is conceived from the influx of the Divine good into the affection of rational truths; the good which is thence in the rational is called a “brother,” and the truth which is thence, a “sister.” But this will be better seen from what is said by Abraham in verse 12 of this chapter: “and moreover truly she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.”
