3493. 'And his eyes were becoming dark so that he could not see' means when the Rational wished to enlighten the Natural from the Divine. This is clear from the meaning of 'the eyes' as interior or rational sight, dealt with in 2701, and from the meaning of 'seeing' as recognizing and understanding, dealt with in 2150, 2325, 2807. Consequently when 'the eyes' are said 'to be becoming dark' the meaning is that no discernment exists any longer, in this case no discernment of the things present in the natural. This being the meaning of these words, the fact that the Rational wished to enlighten the Natural from the Divine is meant. What this implies may be seen from the following things stated and shown already about the rational and the natural with man when he is being regenerated: The rational is regenerated before the natural, for the reason that the rational is interior and so closer to the Divine, and also is purer and so more suited to receiving the Divine than the natural is; and for the further reason that the natural has to be regenerated by way of the rational, see 3286, 3288, 3321.

[2] When therefore the rational has been regenerated but not the natural the former in that case seems to itself to be made dark, for no correspondence exists between the two. Actually the rational receives its sight from the light of heaven, whereas the natural receives its sight from the light of the world; but unless a correspondence exists between the two the rational is unable to see anything that is in the natural. Everything there is like shadow or even like thick darkness. But once a correspondence does exist, things that are in light in the natural are then apparent to the rational, for things that belong to the light of the world are then enlightened by those that belong to the light of heaven, which are so to speak shining through. But these matters are more clearly evident from what has been stated and shown already about correspondence see 2987, 2989-2991, 3002, 3138, 3167, 3222, 3223, 3225, 3337, 3485. Through what is stated and shown in these paragraphs one may grasp to some extent that the words 'Isaac's eyes were becoming dark so that he could not see' mean that the Rational wished to enlighten the Natural from the Divine, that is to say, to make even the Natural Divine, for the subject in the highest sense is the Lord. Light is thereby shed on this matter by what occurs with man when he is being regenerated and which has been described already; for man's regeneration is an image of the Lord's glorification, 3043, 3138, 3212, 3296, 3490.

3296. 'And the greater will serve the less' means that the good of truth must for a time be subordinate. This is clear from the meaning of 'the greater' as good, from the meaning of 'serving' as being subordinate, and from the meaning of 'the less' as truth. This matter may be seen from what follows, being described there by means of Esau and Jacob. For as has been stated, 'Esau' represents good, and 'Jacob' truth. The rise of a struggle or conflict over priority and over lordship is described in the internal sense by Jacob's stealing the birthright from Esau and also the blessing. But the fact that this situation would last for a time only is evident from Isaac's prophecy concerning Esau,

And by your sword you will live, and you will serve your brother; and it will be, when you have dominion over him, that you will break his yoke from above your neck. Genesis 27:40.

[2] The fact that the things said in this verse have an internal sense, and that without that internal sense nobody can know what they mean, is quite evident, that is to say, what is meant by 'two nations are in your womb, and two peoples will be separated from your bowels', and by '[one] people will prevail over [the other] people, and the greater will serve the less'. The fact that they do mean the things that have been stated is clear from what follows where the subject is dealt with extensively. Furthermore one can scarcely credit that these statements embody such things unless one knows about good and truth, about the birth of the first from the second, and about the change of state with a person when being regenerated. In the internal sense the subject is indeed the Lord, here how the Lord made His Natural Divine. But in the representative sense the subject is the regeneration of man, for man's regeneration is an image of the Lord's glorification, 3043, 3138, 3212 - that is, in regeneration one sees as in a certain image the manner in which the Lord glorified His Human, or what amounts to the same, made it Divine. For as the Lord changed completely His human state into a Divine one, so also does the Lord when He is regenerating man change his state completely, for He turns his old man into a new man.
