6256. 'And the eyes of Israel were weak' means his obscurity of discernment. This is clear from the meaning of 'the eyes' as the sight of the understanding, dealt with in 2701, 4087, 4379, 4403-4421, also meant by 'seeing', as above in 6249; from the representation of 'Israel' as spiritual good within the natural, dealt with above in 6253; and from the meaning of 'being weak', when used in reference to the eyes, as obscurity, thus obscurity of discernment. The reason Why Israel's discernment had become obscure when he blessed Joseph's sons was that he had reached the final phase of his representation, though a more general reason is that an obscurity of perception exists in the spiritual good which 'Israel' represents; for that good comes from the natural, in which inferior natural light predominates, not superior heavenly light in which spiritual and celestial good from the rational dwells. Such is the nature of the external man, also called the natural man. When the expression 'spiritual good from the natural' is used, people whose good is such are meant. They are those who belong to the Lord's spiritual Church, which also is why 'Israel' represents that Church, 4286; and compared with celestial people, members of that Church, who are spiritual people, live in obscurity, see 2708, 2715, 2716, 2718, 2831, 2849, 2935, 2937, 3246, 4402. And since they live in obscurity they also put the truth of faith in the first place, even as Israel did here, in that he made Ephraim take precedence over Manasseh.

[2] The reason why spiritual people believe that the truth of faith takes precedence is that it is by means of truth that they are led on to good, 2954; and while they are being led to it they have no perception of good because good flows from within into an affection for truth, and so does not enter their discernment until they have been regenerated. This also explains why they call the good deeds of charity the fruits of faith, though little concern is shown for such fruits by those who suppose that faith alone without good works saves a person, even in the final hour when he dies, irrespective of the life he had led before that. This way of thinking is clearly an obscurity of discernment regarding goodness and truth. But be that as it may, those who make faith take precedence over charity on doctrinal grounds and yet lead a charitable life are people who belong to the Lord's spiritual Church and are saved. For in life they make the good of charity take precedence, but in doctrine the truth of faith.

2935. 'Let him give me the cave of Machpelah [which is his]' means the obscurity of faith [that was theirs]. This is clear from the meaning of 'a cave' as obscurity, dealt with in 2463, and from the meaning of 'Machpelah' as faith which is enveloped in obscurity. The reason 'a cave' means obscurity is that it is a place filled with darkness. When reference is made to a mountain cave - as in Genesis 19:30, where it is said that Lot lived in a mountain cave - obscurity as regards good is meant, but when reference is made to the cave in the field of Machpelah obscurity as regards truth is meant. Here, because the expression 'the cave of Machpelah' is used - Machpelah being the field at the end of which the cave was situated - an obscurity as regards truth, or what amounts to the same, as regards faith is meant. From this it is also evident that Machpelah is faith which is enveloped in obscurity.

[2] Those who are being regenerated and becoming spiritual are very much in obscurity as regards truth. With them good from the Lord is indeed flowing in, but truth less so. Consequently a parallelism and correspondence exists with man between the Lord and good, but not between Him and truth, see 1832. The chief reason for this is that men do not know what good is, and if they did know they would still not believe it at heart. And as long as their good is enveloped in obscurity, so too is their truth, for it is from good that all truth springs. Or to be more explicit, the idea that the Lord is Good itself, and that everything which in itself is a manifestation of love to Him and of charity towards the neighbour is good, and that everything which declares and confirms this is truth, they do not know except in an extremely obscure way. Indeed they even entertain doubts, and allow reasonings to enter in against those considerations. And as long as their state is such, the light of truth from the Lord cannot flow in. Indeed they think of the Lord as they do of another human being and not of Him as God; and they model their idea of love to Him on some worldly kind of love. What genuine affection that stems from charity towards the neighbour is they scarcely know at all, or even what charity is and what the neighbour is. Yet these are essentials. From this one may recognize the great obscurity in which spiritual people are and which is all the greater before regeneration has taken place, which state is the subject here.
