3599. And Isaac his father answered and said unto him. That this signifies perception concerning natural good, that it would be made Divine, is evident from the signification of Isaac, as being the Lord’s Divine rational as to the Divine good therein (n. 3012, 3194, 3210); and from the signification in the historicals of the Word of “saying,” as being to perceive, which has already been frequently treated of; and from the representation of Esau, to whom he spoke, as being natural good, concerning which also much has been already said. That it should be made Divine, is evident from the blessing, now to be considered. It was said above that Esau represents the Lord’s Divine natural as to Divine good, and Jacob His Divine natural as to Divine truth; but here, that Esau represents the natural good which was to be made Divine; and in what goes before, that Jacob represented the natural truth which also was to be made Divine. How the case herein is may be seen from what was said above (n. 3494, 3576); but that it may become still clearer, a few words shall be added.

[2] The natural good which Esau first represents is the natural good of the Lord’s infancy, which was Divine from the Father, but human from the mother; and insofar as it was from the mother it was imbued with hereditary evil; and being such, it could not be at once in an order capable of receiving the Divine that was inmostly within it; but had first to be reduced into order by the Lord. The case is the same with the truth represented by Jacob; for where there is good there must be truth in order for there to be anything; all that which is of thought, even with infants, is of truth, adjoined to the will part which is of good. Wherefore after the Lord had reduced the natural as to good and as to truth in Himself into order, so that it might receive the Divine, and that thus He Himself might inflow from His Divine, and after by successive steps He had expelled all the human that was from the mother; then Esau represents the Lord’s Divine natural as to good, and Jacob His Divine natural as to truth.

[3] But Esau and Jacob represent the Divine good and Divine truth of the Lord’s Divine natural as conjoined with each other like brothers, which Divine good and Divine truth considered in themselves are nothing else than one simultaneous power for the formation and reception of actual good and truth. This actual good and truth are treated of later. From all this it is evident what great arcana are contained in the internal sense of the Word, which arcana are such that not even their most general points fall into the understanding of man; as possibly may be the case with the things just stated; and how then can the innumerable particulars relating thereto do so? Yet are they well adapted to the understanding and apprehension of the angels, who concerning these and the like things receive from the Lord heavenly ideas illustrated by representatives of ineffable loveliness and bliss; from which some conception may be formed of the nature of angelic wisdom, yet remotely, because such things are in the shade of the human understanding.

1901. It may be that I shall be built up by her. That this signifies that in this way the rational could be born, may be seen from the signification of being “built up,” when predicated of generation, and thus without explication. By “Sarai,” as has been said, is signified intellectual truth which has been adjoined as a wife to good. Intellectual truth, which appertains to the inmost, is altogether barren, or like a childless mother, when as yet there is not any rational into which and through which it may inflow; for without the rational as a medium intellectual truth cannot inflow with any truth into the exterior man, as may be seen from the case of little children, who can know nothing whatever of truth until they have been imbued with knowledges; but, as before said, the better and more perfectly they are imbued with knowledges, so much the better and more perfectly can intellectual truth which appertains to the inmost, or to good, be communicated.

[2] This intellectual truth, represented by Sarai, is the spiritual itself which flows in through heaven, and this by an internal way, and with every man; and it continually meets the knowledges that are insinuated by means of the things of sense, and are implanted in the memory. Man is not aware of this intellectual truth because it is too pure to be perceived by a general idea. It is like a kind of light that illuminates the mind, and confers the faculty of knowing, thinking, and understanding. As the rational cannot come into existence except by means of the influx of the intellectual truth represented by Sarai, it stands related to this truth as a son. When the rational is being formed from truths that have been adjoined to good, and still more when it is being formed from the goods from which are truths, it is then a genuine son. Before this it is indeed acknowledged as a son, yet not as a genuine son, but as coming from a handmaid; and still it is adopted, which is the reason why it is here said that she might be built up by her.
