8206. 'And the waters were a wall for them on their right and on their left' means that they were held back from falsities on every side. This is clear from the meaning of 'the waters' - the waters of that sea - as falsities arising from evil, dealt with in 8137, 8138; from the meaning of 'being a wall for them' as being held back from those falsities, dealt with below; and from the meaning of 'on their right and on their left' as on every side. The reason why 'being a wall for them' - when said of 'the waters', by which falsities are meant - denotes being held back from falsities is that the situation with a person is as follows: When he is maintained by the Lord in goodness and truth falsities and evils are removed. Having been removed they stand around him like a wall, for they cannot enter the area where goodness and truth are. The reason for this is that goodness and truth have the Lord present within them, and the Lord's presence repels evil and falsity, on every side; for goodness and truth are the complete opposites of evil and falsity and therefore cannot exist together with them without one destroying the other.

[2] Goodness accompanied by truth destroys, that is, removes evil accompanied by falsity, because goodness is from God and consequently possesses all power, whereas evil is from hell and therefore possesses no power at all. Goodness acts on internal levels, whereas evil acts on external ones. When the evils accompanied by falsities residing with a person are removed they stand around him, as stated, like a wall. They are constantly attempting to rush in on him, but they cannot do so because the Lord's presence, residing in the goodness and truth, holds them back. These are the considerations meant by the waters being like a wall for them on the left and on the right. Regarding a person's being held back from evil and falsity through being maintained by the Lord in goodness and truth, see 1581, 2406, 4564. Yet no one can be held back from evil and maintained in good unless he has received that ability through exercising charity in the world. A life of good, that is, a life led in accordance with the truths of faith, and therefore an affection for or a love of good, achieves this. The person who has a love of and affection for good as a result of the life he leads can be in a sphere of goodness and truth, but not one who through the life he leads has taken on the nature of evil.

4563. 'Deborah, Rebekah's nurse, died' means that hereditary evil was cast out. This is clear from the meaning of 'dying' as the end or something ceasing to be such as it has been, dealt with in 494, 3253, 3259, 3276, and here therefore, since the subject is hereditary evil, that this was cast out; and from the representation of 'Deborah, who was Rebekah's nurse' as hereditary evil. Inasmuch as she nourishes and suckles an infant, 'a nurse' strictly speaking means the instilling of innocence by means of what is celestial-spiritual, for 'milk' means that which is celestial-spiritual, 2184, and the infant whom she suckles means innocence, 430, 1616, 2126, 2305, 2306. But in this verse 'Deborah, Rebekah's nurse' means that which was received from the mother and nourished from infancy. This was the hereditary evil from the mother which the Lord fought against, as may be seen from what has been shown regarding that heredity, 1414, 1444, 1573, which heredity He cast out, so that at length He was not Mary's son, 2159, 2574, 2649, 3036.

[2] It is well known that a person derives evil from both parents and that this evil is called hereditary evil. He is therefore born with that evil, but it does not show itself until he grows up and acts from his understanding and his will based on his understanding. In the meantime it lies hidden, especially during early childhood. Now because in the Lord's mercy no one can come to be blamed for his hereditary evil, only for the evil of his own doing, 966, 2308, and hereditary evil cannot become evil of his own doing until he acts from his own understanding and his own will, young children are therefore guided by the Lord by means of young children and angels. It is for this reason that they are seen to live in a state of innocence; yet hereditary evil lies hidden within each particular thing they do, 2300, 2307, 2308. This hereditary evil even provides them with nourishment, that is, it acts like a nurse until they reach the age of discretion, 4063. Then, if they are being regenerated, they are brought by the Lord into the state of a new infancy, and at length into heavenly wisdom, and so into genuine infancy, which innocence is; for genuine infancy, or innocence, dwells within wisdom, 2305, 3183. The difference is that the innocence of infancy is present outwardly and hereditary evil inwardly, whereas the innocence of wisdom is present inwardly and evil - hereditary and that of the person's own doing - outwardly. From these considerations, and many others mentioned previously, it is evident that hereditary evil serves so to speak as nourishment from earliest infancy to the age of the new infancy. This explains why 'a nurse' means hereditary evil, as well as meaning the instillation of innocence by means of that which is celestial-spiritual.

[3] Since the arrangement or ordering of truths by good within the Lord's Natural, and consequently the progression towards aspects more interior, 4536, is the subject in the internal sense of this chapter therefore the casting out of hereditary evil is dealt with too. This is the reason why in this verse the death of Deborah, Rebekah's nurse, and her burial under an oak tree are recorded, which are matters that would be too unimportant to interrupt the sequence of events described here if they did not embody the kind of the things that have been mentioned.

[4] The actual arcanum meant specifically by Rebekah's nurse cannot as yet be disclosed. One must first know about the nature of the influx of the rational into the natural, which is an influx from the good of the rational directly into the good of the natural, and an influx from the good of the rational indirectly by way of the truth there into the good of natural truth. 'Rebekah' is the truth of the rational, 3012, 3013, 3077, whereas 'Isaac' is the good of the rational, 3012, 3194, 3210. 'Esau' is the good of the natural resulting from direct influx from the good of the rational, meant by 'Isaac', and 'Jacob' is the good - that is, the good of natural truth - resulting from an indirect influx through the truth of the rational, meant by 'Rebekah'. Regarding this indirect and direct influx see 3314, 3573. This must be known first before anyone can have specific knowledge of the arcanum why 'Rebekah's nurse' means and describes hereditary evil here. It is from such knowledge about influx that one is able to see the nature of that hereditary evil.
