In Ezekiel 26:11, this signifies the love of learning or intellectual things. (Arcana Coelestia 3727)

In Revelation 6:2, this signifies the love of understanding the Word. (Apocalypse Revealed 298)

In Zechariah 12:4, this signifies that the intellectual should be filled with falsities. (Arcana Coelestia 2383[2])

In general, 'a horse' signifies knowledge or understanding of the Word. In an opposite sense it signifies the understanding of the Word falsified by reasonings, and likewise destroyed from self-derived intelligence. 'A dead horse' signifies no understanding of truth from the Word.

5340. 'And he gathered all the food of the seven years' means the preservation of truth linked to good, multiplied in the initial phases. This is clear from the meaning of 'gathering' here as preserving (for it says that he gathered it and laid it up in the cities, in the midst of them, which means that he stored it in the interior parts and thereby preserved it; for it was put to use in the years of famine); from the meaning of 'the food' as everything by which the internal man is nourished, namely good and truth, as may be recognized from the correspondence of earthly food which nourishes the external man with spiritual food which nourishes the internal man. Here therefore truth linked to good is meant, because this is what is preserved and stored away in a person's interior parts. 'Seven years' means the initial phases, when truths become multiplied, 5339. From all this it is evident that 'he gathered all the food of the seven years' means the preservation of truth linked to good, multiplied in the initial phases.

[2] The expression 'the preservation of truth linked to good' is used, but because few are aware of what truth linked to good is, let alone of how and when truth becomes linked to good, let something therefore be said about this. Truth comes to be joined to good when a person finds joy in doing good to his neighbour for truth and goodness' own sake, and not for any selfish or worldly reason. When that affection moves a person the truths he hears or reads or thinks about become joined to good; and this can usually be seen in an affection for truth which has that end in view.
