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.
Roof
The roof of a house is its highest point, and the part most exposed to the sun. So it makes sense that in the Bible, “roof” represents what is inmost in a person -- the part that is closest and most in contact with the Lord. This inmost part is, in everyone, a love or affection rather than a truth or idea. This makes sense if you think about it: Even the greatest thinkers are driven by a love of ideas -- our character is ultimately a matter of what we care about, not what we think. Following this, then, “roof” represents our most deeply felt affection for what is good and true.
