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 11:7-9
7
The cow and the bear will graze. Their young ones will lie down together. The lion will eat straw like the ox.
8
The nursing child will play near a cobra's hole, and the weaned child will put his hand on the viper's den.
9
They will not hurt nor destroy in all my holy mountain; for the earth will be full of the knowledge of Yahweh, as the waters cover the sea.
