4570. 'But indeed Israel will be your name' means the nature of the internal natural, or the nature of the spiritual aspect of it, represented by 'Israel'; 'and He called his name Israel' means the internal Natural or the celestial-spiritual aspect of the Natural. This is clear from the meaning of 'name' as the essential nature, dealt with just above in 4568, and from the meaning of 'Israel' as the internal aspect of the Lord's natural and also the celestial-spiritual aspect of the Natural. No one can know why Jacob was called Israel unless he knows what the internal natural is and what the external natural is, and in addition what the celestial-spiritual aspect of the natural is. These matters have in actual fact been explained already, when Jacob was named Israel by the angel; but because they are the kind of things about which people know little, if anything, they need to be explained again.

[2] Two quite distinct and separate degrees exist in man - the rational and the natural. The rational constitutes the internal man and the natural the external; but the natural, like the rational also, has an external aspect of its own and an internal one. The external aspect of the natural is composed of the physical senses and of the impressions received from the world through these senses immediately. By means of his sensory impressions a person is in touch with things belonging to the world and to the body; and people who are confined solely to this natural are called sensory-minded because their thought goes scarcely at all beyond sensory experience. But the internal part of the natural is made up of ideas inferred - by the use of analysis and analogies - from what is in the external, even though it draws on and derives its ideas from sensory impressions. So the natural is in touch through the senses with things belonging to the world and to the body, and through ideas, arrived at by the use of analogy and analysis, with the rational, thus with things belonging to the spiritual world. Such is the composition of the natural. There is another part that exists between and has links with both of them - with the external aspect and with the internal - and so is in touch through the external with things in the natural world, and through the internal with those in the spiritual world. This external natural is represented specifically by 'Jacob', and the internal natural by 'Israel'. The situation is similar with the rational; that is to say, there is an external aspect and an internal, and a further one between the two. But this, in the Lord's Divine mercy, is to be discussed where Joseph is the subject, for 'Joseph' represents the external aspect of the rational.

[3] What the celestial-spiritual is however has been stated several times already - that essentially the celestial is good and the spiritual truth, so that the celestial-spiritual is that which is good resulting from truth. Now because the Lord's Church is both external and internal, and internal features of the Church had to be represented by the descendants of Jacob through things of an external nature, Jacob could not therefore be called Jacob any longer, but was called Israel - see what has been introduced already about these matters in 4286, 4292. Further to this it should be recognized that the terms celestial and spiritual are used both of the rational and of the natural. Celestial is used when people receive good, and spiritual when they receive truth from the Lord; for the good which flows from the Lord into heaven is called celestial, and the truth is called spiritual. In the highest sense the naming of Jacob as Israel means that the Lord progressed towards more interior aspects and made the Natural within Him Divine, both the external aspect of it and the internal. For in the highest sense that which is represented is the Natural itself.

4279. The explanations given so far to these two verses present what they contain in the highest sense and in the internal sense. But in the lower sense they have a different meaning. There the essential nature of Jacob and his future descendants is the subject. Because the Word originates in the Lord and comes down from Him by way of heaven to man its nature is therefore such that it is Divine in every detail. And as it has come down from the Lord so it goes up, that is, is raised up to Him, returning by way of the heavens. It is well known that there are three heavens, and that the inmost is termed the third heaven, that the middle one is called the second heaven, while the lowest is referred to as the first heaven. Consequently since it goes up by the same path as it comes down the Word as it exists in the Lord is Divine, celestial as it exists in the third heaven since that heaven is the celestial heaven, spiritual as it exists in the second heaven since that heaven is the spiritual heaven, but celestial-natural and spiritual-natural as it exists in the first heaven, which is also given the names celestial-natural and spiritual-natural. As it exists in the Church with man however, the Word in the sense of the letter is natural, that is, worldly and earthly.

[2] From this one may see the nature of the Word and what happens to it when a person reads it with a holy mind, that is, one in whom good and truth are present. For when he reads it, it is seen by him as something existing in this world or as a historical document, but which nevertheless is inwardly holy. But in the first heaven it is seen as something celestial-natural and spiritual-natural, which however is inwardly Divine. In the second heaven it is spiritual, and in the third celestial; and in the Lord it is Divine. The sense in the Word varies according to whatever heaven it may be. The highest sense of the Word, whose subject is the Lord, exists for the inmost or third heaven; the internal sense, whose subject is the Lord's kingdom, exists for the middle or second heaven; the lower sense, in which the internal sense is narrowed down to the nation referred to there, exists for the lower or first heaven. But the lowest or literal sense exists for man while he is still living in the world. Yet man's nature is such that the more interior sense, and also the internal and highest sense, can be communicated to him. For man has communication with the three heavens; indeed he is created on the pattern of the three heavens, so much so that when love to the Lord and charity towards the neighbour constitute his life he is heaven in miniature. Consequently such a person has the Lord's kingdom within him, as the Lord Himself teaches in Luke,

Behold, the kingdom of God is within you. Luke 17:21.

[3] These things have been stated so that people may know that the Word contains not only a highest sense and an internal sense but also a lower sense, and that in this sense, that is to say, in the lower, the internal sense is narrowed down to the nation referred to there; and when this is done that sense is plain to see from the train of thought. At present it is self-evident that the man's wrestling with Jacob and the disjointing and displacing of his thigh also has reference to Jacob and his descendants. That being so, let these same words be explained according to that sense. In what follows below this sense will be termed the INTERNAL HISTORICAL SENSE. It will be called this for the added reason that it is quite usual for this sense to be represented from time to time in the first heaven as something animate and taking visible form, as also I have been allowed to see several times. See the explanation given already in the latter part of 4272.
