8203. 'And made the sea into dry ground' means the dispersing of falsity. This is clear from the meaning of 'the sea' as falsity, as just above in 8201; and from the meaning of 'making into dry ground' as dispersing it. 'Passing through on dry ground', said in connection with the waters of the sea when they had been removed, means doing so in safety and without falsity flowing in, see above in 8185.

3217. When angels' discussion has to do with the understanding part of the mind, horses appear in the world of spirits below them, that is, in the communities which correspond to them. The size, shape, colour, and stance of the horses depends on the ideas which the angels have concerning the understanding. The horses also carry differing adornments. There is also a place quite deep down and a little towards the right which is called the abode of the intelligent. There horses are seen constantly, the reason being that those there are engaged in thought about the understanding; and when the angels who are engaged in a discussion about the understanding flow into the thoughts of those spirits, horses are seen. From this I have come to see what was meant by the horses seen by the prophets, and also by the horses mentioned in the Word, namely aspects of the understanding, 2760-2762.
