Arcana Coelestia # 9953
9953. 'And his sons with him' means such a state there in the outward things emanating from that [Divine Good]. This is clear from the meaning of 'to clothe' as to bring about a state such as is represented by garments, dealt with immediately above in 9952, at this point that which is represented by the garments of Aaron's sons, which is the state in the spiritual kingdom of the outward things emanating from Divine Truth. For that which emanates is meant by 'sons', and so too by their 'garments', as accords with what has been stated just above in 9950.

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.
