3819. 'The name of the elder was Leah' means the nature of the affection for external truth; 'and the name of the younger Rachel' means the nature of the affection for internal truth. This is clear from the representation of 'Leah' as the affection for external truth, and of 'Rachel' as the affection for internal truth, both dealt with in 3793; and from the meaning of 'the name' as the nature of, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006. Leah is called 'the elder' because external truth is learned first, and Rachel 'the younger' because internal truth is learned from then on after that; or what amounts to the same, a person first of all feels an affection for external truths, and from then on after that an affection for internal truths. external truths provide the basic outline for internal truths, for they are the general outlines into which particular details are added. Unless a person has a general outline of the idea of a thing he does not make sense of any particular aspect of it. This explains why the literal sense of the Word contains general truths but the internal sense particular truths. General truths are called external, but particular truths internal. And because truths devoid of affection are not truths because there is no life to them, the affections for them are therefore meant when external and internal truths are referred to.

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.
