Babylon was an ancient city built on the Euphrates river in what is now southern Iraq. It once was the capital of a great empire which at one point conquered the land of Judah as mentioned in the second book of Kings and in Daniel. But the river changed its course and the city was abandoned long ago. Both the historic city in Mesopotamia and the parable city with its tower, mentioned in Genesis, represent the same thing, a worship that appears holy in externals, while the internals are profane. This representation expands to mean a church whose leaders use this kind of worship to gain dominion over others for their own gain and for the gain and power of the church. The city itself is the doctrinal structure that supports this kind of worship and dominion.

437. And the sound of their wings was like the sound of many horse-drawn chariots rushing into battle. This symbolizes their reasonings, as though founded on doctrinal truths from the Word fully understood, which they had to ardently defend.

The sound of wings symbolizes reasonings, because to fly means, symbolically, to perceive and teach (nos. 245, 415). Chariots symbolize doctrinal teachings, as we are about to show. Horses symbolize an understanding of the Word (no. 298), and many horses a full understanding. Plainly to rush into battle symbolizes an ardor to fight.

That a chariot symbolizes doctrine is clear from the following passages:

The chariots of God are twenty thousand, thousands of peaceful ones, the Lord among them... (Psalms 68:17)

(Jehovah) makes the clouds His chariots, He walks on the wings of the wind. (Psalms 104:3)

O Jehovah..., ...You ride on Your horses, Your chariots are salvation. (Habakkuk 3:8)

...behold, Jehovah will come with fire, and like a whirlwind His chariots... (Isaiah 66:15)

You shall be filled at My table with horses and chariots... (Thus) I will set My glory among the nations. (Ezekiel 39:20-21)

I will cut off the chariot from Ephraim and the horse from Jerusalem. (Zechariah 9:10)

I will overthrow the throne of kingdoms... I will overthrow the chariots and those who ride in them. (Haggai 2:22)

...set a watchman, let him declare what he sees. He saw therefore a chariot, a pair of horsemen..., a chariot of camels..., and... the chariot of a man... And he... said, "Babylon is fallen, is fallen!" (Isaiah 21:6-7, 9)

Since Elijah and Elisha represented the Lord in respect to the Word and thus symbolized doctrine drawn from the Word, as did all the prophets (no. 8), therefore they were called "the chariots of Israel and its horsemen;" and for the same reason Elisha saw Elijah taken up into heaven in a chariot of fire, and Elisha's servant saw chariots and horses of fire around Elisha (2 Kings 2:11-12; 6:17; 13:14).

See also elsewhere where chariots are mentioned, as in Isaiah 31:1; 37:24; 66:20; Jeremiah 17:25; 22:4; 46:2-3, 8-9; 50:37-38; 51:20-21.
