57. 'The plant yielding seed' is every truth that looks towards a use. 'The tree in which there is fruit' is the good that accompanies faith. 'Fruit' is what the Lord gives to the celestial man, while 'seed', the source of the fruit, is what He gives to the spiritual man. This is why it is said that 'the tree producing seed will be for you for food'. That celestial food is called 'fruit from a tree' is clear from the next chapter where the subject is the celestial man. Here let just that be mentioned which the Lord spoke through Ezekiel,

Beside the river there is rising up upon its bank, on this side and on that, every tree for food. Its leaf will not fall nor its fruit fail. It is re-born monthly, for its waters flow out from the Sanctuary, and its fruit will be for food, and its leaf for medicine. Ezekiel 47:12.

'Waters from the Sanctuary' means the life and mercy of the Lord, who is the Sanctuary; 'fruit' means wisdom, which is food for them; 'leaf' is intelligence, which is given them for a use, which is called 'medicine'. Spiritual food however is called 'a plant', as stated through David,

[Jehovah is] my Shepherd, I shall not want; He makes me ¹ lie down in green pastures. ² Psalms 23:1-2.

Footnotes:

676. And there were killed in the earthquake names of men seven thousand, signifies that in that change of state all truths of good with them perished, and thus all things of heaven and the church. This is evident from the signification of "to be killed," as being to be killed spiritually, which is to perish by evils and falsities (See above, n. 315, 547, 572, 589); also from the signification of "earthquake," as being a change of state of the interiors with those who are of the church (See above, n. 674); also from the signification of "the names of men," as being the truths of good and the consequent understanding of truth (of which presently); and from the signification of "seven thousand," as being all things of heaven and the church, for "seven" signifies all things, and is predicated of the holy things of heaven and the church (of the signification of this number see above, n. 257; and its signification is retained when it is multiplied by ten, or one hundred, or one thousand, for these numbers signify all things. From this it can be seen that "there were killed in the earthquake names of men seven thousand" signifies that in that change of state all truths of good perished, and thus all things of heaven and the church.

[2] That "the names of men" signify the truths of good and the consequent understanding of truth can be seen from the signification of "name," as being the quality of a thing or state with man; and from the signification of "man," as being intelligence, thus also the understanding of truth. "Name" signifies the quality of a thing or state with man because in the spiritual world there are no names of persons as in the natural world. In the spiritual world all are named according to the quality of their life, thus with a difference within societies and out of them. Within the societies the quality of each one's state of life is constant, for each one there dwells in a quarter and also at a distance from the center according to the quality of his affection and of his intelligence; therefore his name is in accord with this quality. When, therefore, the name of anyone in a society is heard his quality is also recognized. This is why "name" signifies in the spiritual sense the quality of a thing and of a state of life. But outside of societies this naming according to one's state of life is not constant; for before a man-spirit enters into any society he passes through many states in order that he may put off the things that disagree with his ruling love and put on such as agree with it, and yet everyone is named according to the state in which he is, and also according to the idea and perception of what his state is. That names in the spiritual world are uttered spiritually may be seen above n. 102; therefore "name" signifies in the Word what the state of the life is n. 148. So, too, "the name of Jehovah" and "the name of the Lord" signify all things by which He is worshipped, thus all things of love and faith (n. 102, 135); and "man" signifies in the Word the spiritual affection of truth, and thence the understanding of truth (n. 280, 546). From this it is clear what "the names of men" signify.

[3] Why the truths of good and thus the understanding from them were destroyed by the notable change of state which was signified by "a great earthquake" has been told in the preceding article, namely, that at the end of the church, when the Last Judgment is at hand, those who are spiritually good are taken away from those who are only naturally good; and when this is done, then also from the latter all truths of good and consequently all understanding of truth are also taken away; for with the natural, who are destitute of anything spiritual, truths and goods reside in their externals, but falsities and evils in their internals; therefore when the good with whom they had communication as to externals are taken away the externals also are taken away and the internals are disclosed, and these, as has been said, are filled with mere falsities of evil. This is why these words signify that all truths of good and all understanding of truth perished with those who remained.
