476. And have made their robes white in the blood of the Lamb, signifies the implantation of Divine truth from the Lord. This is evident from the signification of "making robes white," as meaning to put off falsities and to put on truths, for "white" and "to be made white," are predicated of truths, and these are signified by "robes." (That "white" and "to be made white," are predicated of truths, see above, n. 196; and that "robes" signify truths in general see above, n. 395.) It is said "made their robes white," because the garments of those who are in falsities appear in the spiritual world dusky and also spotted, and the garments of those who are in temptations appear filthy; but as soon as they emerge from temptations, as they have then been imbued with Divine truths, white and shining garments without spots appear upon them, as was mentioned just above. This is why "they have made their robes white" signifies that they have put off falsities and put on truths. The above is evident also from the signification of "the blood of the Lamb" as being Divine truth proceeding from the Lord (of which above, n. 329 e New Jerusalem 293, 294, and in the extracts there from the Arcana Coelestia.) This can be seen from this also, that the garments of angels appear glistening from what is white and bright, not from faith in and thought about the blood of the Lord on the cross, but from Divine truth with them from the Lord; for, as was said above, their garments are all in accord with the truths with them; nor is any angel permitted to think of the Lord's passion, but only of His glorification, and of the reception by Him of the Divine.); and because in temptations falsities are shaken off, and truths are implanted, so in general, "they have made their robes white in the blood of the Lamb" signifies the implantation of Divine truth from the Lord. In the sense of the letter of the Word, "the blood of the Lamb" means the passion of the cross, but in the internal or spiritual sense it means Divine truth proceeding from the Lord; for it is by this that man is purified from falsities and evils, that is, his garments are made white. The passion of the cross was the Lord's last temptation, by which He fully subjugated the hells, and glorified His Human; and when this was accomplished and completed, the Lord sent the Comforter, the Spirit of Truth, by which is meant Divine truth proceeding from His glorified Human, as the Lord teaches in John (John 7:39) and elsewhere. It is by means of Divine truth, when it is received, that man is reformed and regenerated by the Lord and saved, and not by the shedding of blood on the cross. (On this more may be seen in The Doctrine of the New Jerusalem 293-294.)

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.
