Arcana Coelestia #4108
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.

3211. 'And he took Rebekah, and she became his wife, and he loved her' means the joining together, that is to say, of good and truth. This becomes clear without explanation. The reason why it is said, that Rebekah became his wife (mulier), not his wife (uxor), is that no marriage existed between rational Good on one side and Truth summoned from the natural and made Divine on the other, only a covenant similar to the marriage covenant. The Divine Marriage itself within the Lord consists in the union of the Divine Essence with the Human Essence, and of the Human Essence with the Divine Essence, see 2803. This is the reason why Rebekah is called a wife (mulier) and not a wife (uxor).
