Horse
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.
Joel 2:12-13
12
"Yet even now," says Yahweh, "turn to me with all your heart, and with fasting, and with weeping, and with mourning."
13
Tear your heart, and not your garments, and turn to Yahweh, your God; for he is gracious and merciful, slow to anger, and abundant in loving kindness, and relents from sending calamity.
