4108. 'To come to Isaac his father, to the land of Canaan' means so as to be joined to the Divine Good of the Rational, in order that the Human might be made Divine. This is clear from the representation of 'Isaac' as the Divine Rational, dealt with in 1893, 2066, 2083, 2630, and specifically as the Divine Good of the Rational, 3012, 3194, 3210; and from the meaning of 'the land of Canaan' as the Lord's heavenly kingdom, dealt with in 1607, 3481, and in the highest sense - that is, when the subject is the Lord - as His Divine Human, 3038, 3705. From these meanings it is evident that 'to come to Isaac his father, to the land of Canaan' means so as to be joined to the Divine Good of the Rational, in order that the Human might be made Divine.

[2] As regards the joining together of the rational and the natural in man's case, it should be realized that the rational constitutes the internal man and the natural the external man, and that the joining together of these produces the human. The nature of that human is determined by that of the joining together of the two; and they exist joined together when they act as one. And they act as one when the natural acts as the servant and is subservient to the rational. With man this is not possible unless it is done by the Lord, but with the Lord He did it by Himself.

2066. 'And I will also give you a son by her' means the Rational. This is clear from the meaning of 'a son' as truth, dealt with in 489, 491, 533, 1147. And because the whole of the rational originates in truth, 'a son' here means the rational. The Lord's first rational was represented and meant by Ishmael, born from the servant-girl Hagar. This was dealt with previously in Chapter 16. The second Rational, which is the subject here, is represented and meant by Isaac who was to be born from Sarah. The former, that represented by Ishmael, was the rational that was subsequently cast out of the house, but this latter Rational, which is represented by Isaac, is the one that remained in the house, because it was Divine. This rational is in the Lord's Divine mercy to be described in the next chapter where Isaac is the subject.
