Water generally represents “natural truth,” or true concepts about day-to-day matters and physical things. Since all water ultimately flows into the seas, then, it follows that a sea represents a huge agglomeration of such natural truths -- usually all of the natural truth a person has, or all the natural truth a church has. Water in the sea mixes freely, and is easily stirred up by winds and currents. This is also true of the concepts we hold about natural things -- they are not all related to each other, and when relationships do exist they usually can change without damaging the concepts themselves. Many of the concepts are easily disputed, and arguments can arise like waves on the ocean -- generally with little effect other than a mixing of waters. But the sea also offers great bounty. We draw fish from it (spiritual food), float ships (doctrinal systems) on it, bathe in it (using true concepts to purify ourselves), and the water that evaporates from it and falls as rain (purer forms of truth that can attach to desires for good) makes life possible.

781. "And merchandise of horses, and wagons, and the bodies and souls of people." This symbolically means that all of these things depend on an understanding of the Word and on doctrine drawn from it, and on the goods and truths in the Word's literal sense, which these Roman Catholics do not possess, because they have falsified and adulterated the Word by using the things in it contrary to their real meaning in order to gain dominion over heaven and the world.

The valuables here follow the preposition "of," because they involve all of the things that go before. That horses symbolize an understanding of the Word may be seen in no. 298. Chariots symbolize doctrine from the Word (no. 437); consequently so do wagons. The bodies and souls of people symbolize goods and truths in the literal sense of the Word, because they have the same symbolism as the body and blood in the Holy Supper. The body in that supper symbolizes the Lord's Divine goodness, and the blood the Lord's Divine truth; and because of this symbolism they also symbolize the Divine good and truth in the Word, because the Lord embodies the Word.

Instead of blood, however, the text here says souls. That is because the soul likewise symbolizes truth (see no. 681 above), and because blood in the Word is called the life or soul (Genesis 9:4-5). "Human lives" in Ezekiel 27:13 has a similar symbolic meaning. So does the "seed of men" in Daniel 2:43.

[2] Horses and wagons have a similar symbolic meaning in Isaiah:

Then they shall bring all your brethren... on horses and in chariots and in wagons, and on mules and on camels, to My holy mountain Jerusalem... (Isaiah 66:20)

This is said of the Lord's New Church, which Jerusalem is, regarding people in it who have an understanding of the Word and doctrine derived from it, which are the horses, chariots, and wagons.

Now because these people of the Roman Catholic religion falsify and adulterate the Word by using it to gain dominion over heaven and the world, the symbolic meaning here is that they do not possess any goods and truths from the Word, and so do not have any in their doctrine either.

Regarding this Jeremiah says the following:

...the king of Babylon has devoured me, has thrown me into confusion; He has made me an empty vessel; He has swallowed me up like a whale; He has filled his stomach with my delicacies... (Jeremiah 51:34-35)

A sword is against the horses (of Babylon), against her chariots, and... against her treasures, so that they are plundered. A drought is upon her waters, so that they are dried up. For the land is one of carved images, and they boast of their dreadful deeds. (Jeremiah 50:37-38)
