3299. And behold twins were in her womb. That this signifies that both were conceived together, is evident from the signification of “twins,” as being both, namely good, which is represented by Esau, and truth, which is represented by Jacob; and from the signification of “in the womb,” as being conception (see above, n. 3293). As to both the good and the truth of the natural being conceived together, the case is this: Whatever is born derives its being from a father and its manifestation from a mother; it must have both in order to become something. The natural as to good is conceived from the good of the rational as a father, and as to truth is conceived from the truth of the rational as a mother (n. 3286, 3288). It is good which gives life, but through truth. Both these are called soul, but still good is principally the soul, while truth clothes it as with a kind of tender vessel or body, so that the good is in the truth. This is what is signified by “twins being in her womb.”
