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.
Matthew 5:19-24
19
Whoever, therefore, shall break one of these least commandments, and teach others to do so, shall be called least in the Kingdom of Heaven; but whoever shall do and teach them shall be called great in the Kingdom of Heaven.
20
For I tell you that unless your righteousness exceeds that of the scribes and Pharisees, there is no way you will enter into the Kingdom of Heaven.
21
"You have heard that it was said to the ancient ones, 'You shall not murder;' and 'Whoever shall murder shall be in danger of the judgment.'
22
But I tell you, that everyone who is angry with his brother without a cause shall be in danger of the judgment; and whoever shall say to his brother, 'Raca!' shall be in danger of the council; and whoever shall say, 'You fool!' shall be in danger of the fire of Gehenna.
23
"If therefore you are offering your gift at the altar, and there remember that your brother has anything against you,
24
leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift.
