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.

2145. 'He was sitting at the tent door' means the holiness which existed with Him at that time, namely the holiness of love, which is meant by 'as the day was getting warmer', dealt with in what follows next. This is clear from the meaning of 'a tent' as holiness, dealt with in 414, 1102, 1566. And for the reason why 'tents' meant forms of holiness, see the same paragraphs. Since the Lord at this time had the perception meant by the oak-groves of Mamre, which is a lower rational perception, yet more interior than that meant by the oak-grove of Moreh, dealt with in 1442, 1443, it is here represented and so is meant by his sitting at the tent door, that is, at the entrance to holiness. As regards perceptions being more interior or less interior, this may be illustrated from the perceptions which the most ancient people had. From these people I have heard that the more they were immersed in mere facts acquired from the objects of hearing and sight the lower their perceptions became; but the more they were raised up from them towards the celestial things of charity and love the more interior these perceptions became, as they were then closer to the Lord.
