[2] That frogs signify reasonings from mere falsities against Divine truths, is evident from the miracle of the frogs in Egypt. For all the miracles performed there signify the plagues or evils with which those are affected after death, who, by the scientifics of the natural man, fight against spiritual goods and truths, and endeavour to destroy them. For by Pharaoh and by the Egyptians were represented and thence signified natural men; and by the sons of Israel, whom they infested and desired to drive back into servitude, were represented and thence signified spiritual men. Thus also by the Egyptians were represented and signified the things pertaining to the natural man, and by the sons of Israel, those pertaining to the spiritual man. The things pertaining to the natural man have reference to evils and falsities, evils to the love, and falsities to the doctrine thereof; and the things that pertain to the spiritual man have reference to the goods that belong to love, and to the truths pertaining to the doctrine thereof. That by frogs are there signified the reasonings of the natural man from falsities against the truths of the spiritual man, is evident from the description of that miracle in Moses:

That he caused the river to bring forth frogs in abundance; and they went up and came into the house of Pharaoh, and into his bed-chamber, and upon his bed, and into the house of his servants, and of his people, and into the ovens and the kneading troughs. And that after they were dead, they were gathered into heaps, and the land stank (Exod. viii. 1, 14).

That frogs here signify the reasonings of the natural man from falsities against Divine truths, is evident from the explanation of all those words in the Arcana Coelestia (n. 7345-7357, 7379-7409).

Also in David:

"He turned their waters into blood, and killed their fish; he caused frogs to come forth upon their lands, into the chambers of their kings" (Ps. cv. 29, 30).

[3] This treats of the plagues in Egypt. By the waters turned into blood are signified truths falsified; by the fishes killed are signified that the scientific truths and knowledges of the natural man perished. By the frogs coming forth upon the land are signified the reasonings of the natural man from falsities; the chambers of the kings signify interior truths, which they perverted by reasonings from falsities, inner chambers denoting the interiors, and kings denoting truths. Similar things are signified by the frogs coming up into the house of Pharaoh, into his bed-chamber, and his bed. From these things it is now evident what is signified by the three unclean spirits like frogs, which went forth out of the mouth of the dragon, of the beast, and of the false prophet.

Continuation concerning the Sixth Precept:-

[4] Those who are in love truly conjugial, after death, when they become angels, return into their youth and adolescence. The males, however worn out with age, become young men; and the wives, however worn out with age, become young women. Each conjugial partner returns into the prime of life and into the joys of the age in which conjugial love begins to intensify life with new delights, and to inspire with joyous activity for the sake of prolification. Into this state, first exteriorly, afterwards more and more interiorly to eternity, a man (homo) comes who had shunned adulteries as sins, and was initiated by the Lord into conjugial love in the world. Because they are always growing more interiorly young, it follows that love truly conjugial increases and enters into the delights and joys provided for it from the creation of the world. These are the delights and joys of the inmost heaven, arising from the love of the Lord towards heaven and the church, and thence from the mutual love of good and truth; from this love every joy in the heavens is derived. The reason why a man (homo) thus grows young in heaven is, that he then enters into the marriage of good and truth. And there is in good an effort of continually loving truth, and in truth there is an effort of continually loving good; and then the wife is good in form, and the man is truth in form. It is from that effort that a man (homo) puts off all severity, senile harshness, mournfulness, and want of vitality, and puts on the activity, gladness, and freshness of youth, from which the effort receives life and becomes joy.

[5] It has been told me from heaven that they have then a life of love, which can only be described as being the life of joy itself. That a man (homo) who lives in the world in love truly conjugial comes after death into the heavenly marriage, which is that of good and truth, springing from the marriage of the Lord with the church, is quite clear from this fact, that from marriages in the heavens, although married partners are there united as on earth, children are not born, but instead of children, goods and truths, and thence wisdom, as said above. This is why by births, nativities, and generations in the Word, in its spiritual sense, are meant spiritual births, nativities, and generations, and by sons and daughters, the truths and goods of the church, and other things, but of a similar kind, by daughters-in-law, mothers-in-law, and fathers-in-law. From these things it can also be clearly seen that marriages on earth correspond to marriages in the heavens, and that a man after death comes into the correspondence, that is, from natural corporeal marriage into spiritual heavenly marriage, which is heaven itself, and the joy of heaven.
