3304. 'And his hand was grasping Esau's heel' means the lowest level of natural good, to which [truth] clung with some power. This is clear from the meaning of 'the hand' as power, dealt with in 878, and as having reference to truth, 3091; from the meaning of 'grasping' as clinging to; from the meaning of 'the heel' as the lowest part of the natural, dealt with in 259; and from the representation of 'Esau' as the good of the natural, dealt with in 3302. From these meanings it is evident that 'his hand was grasping Esau's heel' means the lowest level of natural good, which truth clung to with some power.

[2] The implications of truth clinging with some power to the lowest good of the natural are that when the natural, or the natural man, is being regenerated, the conception of good and truth there is from the rational man, that is, from the spiritual man by way of the rational man, prior to this from the celestial man by way of the spiritual man, and prior to this from the Divine by way of the celestial man. Thus it is an influx which starts with the Divine and, passing through consecutive degrees, terminates in the lowest part of the natural, that is, in the worldly and bodily part. When the lowest natural has been contaminated by what is inherited from the mother, truth is unable to be united to good. It can do no more than cling to it with some power. Nor is truth united to good until the contamination has been eliminated. This is the reason why good but not truth is bred within a human being, and why small children therefore are devoid of all knowledge of truth and why truth has to be acquired through learning and after that joined to good, see 1831, 1832. This also explains why it is said that they struggled together within her, that is, they conflicted, 3289. Consequently when first conceived truth supplants good, as is said regarding Jacob, that he supplanted Esau,

Does he not call his name Jacob, and he has supplanted me these two times. Genesis 27:36.

And in Hosea,

He will make a visitation on Jacob over his ways and requite him according to his deeds; in the womb he supplanted his brother. Hosea 12:2-3.

[3] Those whose attention is fixed solely on the historical details and who cannot take it off these know no more than this, that the details contained here, and also those that have gone before [regarding the circumstances of the twins' birth], foretell what took place between Esau and Jacob, as is also corroborated by what follows. But the Lord's Word is such that the historical details follow their own sequence, while the spiritual details, which belong to the internal sense, follow theirs, so that the historical details are seen by the external man, but the spiritual details by the internal man. This being so a correspondence exists between the two, that is to say, between the external man and the internal man; and this is effected by means of the Word, for the Word serves to unite heaven and earth, as shown many times. Thus when anyone in a holy frame of mind reads the Word, a union is effected of his external man which is on earth with his internal man which is in heaven.

1832. 'But the birds he did not cut apart' means that no such parallelism and correspondence existed in the case of spiritual things. This is clear from the meaning of 'birds' as that which is spiritual, dealt with just above in verse 9, and from the fact that he did not part the birds down the middle, which consequently means that no such parallelism and correspondence existed in their case. By spiritual things, as has often been stated already, are meant all those things that constitute faith, consequently all those things which are matters of doctrine, as these are called matters of faith even though in fact they are not so until they have been joined to charity. Between these and the Lord no parallelism and correspondence exists, for they are not such as flow in through an internal dictate and through conscience - as matters of love and charity do - but such as flow in through the reception of teaching and so through hearing, thus not from what is more internal, but from that which is more external; and in this way they form in man their vessels or recipients.

[2] The majority of these have the appearance of being truths but in fact they are not so - like those things which belong to the literal sense of the Word, being also representatives of truth, and meaningful signs of truth, and so not in themselves truths. Some are even falsities, which nevertheless are able to serve as vessels and recipients. With the Lord however only those exist which are wholly and essentially truths, and therefore no parallelism or correspondence exists involving those apparent truths. Yet they may be rendered suitable to serve celestial things - which are matters of love and charity - as vessels. These apparent truths are what constitute the cloud in the understanding part of the mind, dealt with already, into which the Lord infuses charity and so forms conscience.

[3] Take, for example, people who keep to the sense of the letter of the Word and imagine that it is the Lord who brings on temptation, that it is He who at such times tortures a person's conscience, and who imagine that because He permits evil He is the author of evil, that He thrusts the wicked down into hell, and similar ideas. These are not truths, but apparent truths. And because they are not in themselves truths there is no parallelism and correspondence. Nevertheless the Lord leaves these things in man as they are and in a remarkable fashion adapts them by means of charity so that they may serve as vessels for celestial things. The same applies as well to the worship, the teachings, the practices, even the idols, of honest gentiles. In the same way the Lord leaves these things as they are, yet adapts them by means of charity so that they too may serve as vessels. The same was true of so many of the forms of ritual in the Ancient Church, and subsequently in the Jewish Church. In themselves they were nothing more than religious observances that contained no truth in them and which were tolerated and permitted, even prescribed, because they had been held sacred by parents, and so had been implanted in and impressed upon their minds as truths since they were children.

[4] These and other such things are what are meant by the statement that the birds were not divided. For the things that are once implanted in a person's beliefs and are held sacred, provided they are not contrary to Divine order, are left by the Lord as they are; and although no parallelism or correspondence exists He nevertheless adapts them. The same things were also meant in the sacrifices of the Jewish Church by the birds not being divided, for to divide is to set one part opposite the other so that they exactly correspond. But because those things to which reference has been made are not exactly correspondent, they are in the next life blotted out in the case of those who allow themselves to be taught, and truths themselves are implanted in their affections for good. For the sake of this representation and meaning, birds in the Jewish Church were not divided, as is clear in Moses,

If his gift to Jehovah is a burnt offering of a bird, he is to bring a gift of turtle doves or of young pigeons; he will tear it with its wings, he is not to divide it. Leviticus 1:14, 17.

Likewise in sacrifices for sin, Leviticus 5:7-8.
