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.
Isaiah 9:19-21
19
Through the wrath of the LORD of hosts is the land darkened, and the people shall be as the fuel of the fire: no man shall spare his brother.
20
And he shall snatch on the right hand, and be hungry; and he shall eat on the left hand, and they shall not be satisfied: they shall eat every man the flesh of his own arm:
21
Manasseh, Ephraim; and Ephraim, Manasseh: and they together shall be against Judah. For all this his anger is not turned away, but his hand is stretched out still.
