2093. 'Whom Sarah will bear to you' means Divine Truth joined to Divine Good from which it will come forth into being. This is clear from the representation of 'Sarah' as Divine Truth, dealt with already in 2063, 2081, and from the representation of 'Abraham' as Divine Good, dealt with in 2063 and in various places elsewhere.

[2] The manner in which the Lord's first rational was conceived and born has been stated in the previous chapter where Ishmael, who represented that rational, was the subject. This chapter and the next deal with that Rational which was made Divine by the Lord, something He achieved through the marriage-like conjunction of Divine Good with Divine Truth. The only possible way the first rational can be conceived is by the influx of the Internal Man into the External Man's affection for knowledge. Nor can it be born from anything other than the affection for knowledge, an affection represented by 'Hagar, Sarai's servant-girl', as shown in the previous chapter, in 1896, 1902, 1910, and elsewhere in that chapter.

[3] But the second or Divine Rational is not conceived and born in the same way but by the conjunction of Truth in the Internal Man with Good in the same, and the resulting influx. In the Lord's case this was achieved by His own power derived from the Divine itself, that is, from Jehovah. As stated in various places already, His Internal Man was Jehovah. And Good itself, represented by 'Abraham', belonged to the Internal Man, as also did Truth itself, represented by 'Sarah'. Both were on that account Divine, and from them both the Lord's Divine Rational was conceived and born. Indeed it was conceived and born from the influx of good into truth, and so by means of truth, for the principal element in the rational is truth, as stated above in 2072. Hence the statement here 'whom Sarah will bear to you', which means Divine Truth joined to Good from which it will come into being, and at verse 17 above the statement 'Sarah a daughter of ninety years' means that Truth joined to Good will accomplish this.

[4] With all human beings, since each has been created in the likeness and image of God, something similar yet not comparable takes place, in that his first rational too is conceived and born through the influx of his internal man into the life of his external man's affection for knowledge, but his second rational results from the influx of good and truth from the Lord by way of his internal man. This second rational he receives from the Lord when he is being regenerated, for at that time he senses within his rational what the good and truth of faith are. The internal man with anyone is above his rational, and is the Lord's. This is dealt with in 1889, 1940.

1889. It is similar in this chapter with the names Abram, Sarai, Hagar, and Ishmael. What these include within themselves becomes clear from the Contents and after that from the explanation of each name in what follows. They are however things such as cannot be explained easily and intelligibly, for the subject covered by those names is the Lord's Rational - how it was conceived and born, and the nature of it before it had been united to the Lord's Internal, which was Jehovah. The reason this cannot be explained easily and intelligibly is that people at the present day do not know what the internal man is, what the interior man is, or what the exterior man is. When one speaks of the rational or of the rational man some idea can be formed of these, but when one speaks of the rational as that which lies between the internal and the external, few if any can grasp it. Nevertheless since the subject in the internal sense of this chapter is the way in which the Lord's Rational Man was conceived and born from an influx of the Internal Man into the External Man - for this is the subject embodied within the historical descriptions involving Abram, Hagar, and Ishmael and yet to prevent the ideas presented in the explanation that follows from becoming utterly strange and unintelligible, let it be recognized that with everyone there exists an internal man, there exists a rational man which is situated in between, and there exists an external man, and that these three are quite distinct and separate from one another. For these matters see what has been stated already in 978.
