52. As long as someone is a spiritual man, the dominion over him runs from external man to internal man, as is said here, 'They will have dominion over the fish of the sea, over the birds of the air', and over the beasts, and over all the earth, and over every creeping thing that creeps on the earth'. When however he becomes celestial and does what is good out of love, then the dominion over him runs from internal man to external man. This is how the Lord describes Himself, and so simultaneously the celestial man, who is a likeness of Him, in David,

You have given him dominion over the works of Your hands; You have put all things under his feet, flocks and all cattle, and also the beasts of the field, the birds of the air, ¹ and the fish of the sea, and that crossing the paths of the seas. Psalms 8:6-8.

Here therefore the beasts are mentioned first, the birds next, and the fish of the sea after that, for the reason that the celestial man starts with love which resides in the will. With the spiritual man it is different. With him fish and birds, which have to do with the understanding, the domain of faith, come first, while beasts come afterwards.

647. It is bound to seem strange and very far-fetched to everybody that these details have this meaning, that is to say, that the numbers three hundred, fifty, and thirty mean remnants, and in particular that they were few; also that 'length, breadth, and height' means holiness, truth, and good. But in addition to what has been stated and shown above about numbers at verse 3 of this chapter, where a hundred and twenty means the remnants of faith, this matter may also become clear to anybody from the fact that people who possess the internal sense, as good spirits and angels do, are beyond anything earthly, bodily, or purely worldly, and so beyond anything involving numbers and measurements. Yet the Lord enables them to perceive the Word fully, and to do so quite independently from such concepts. This being so, it becomes quite clear that numbers and measurements embody celestial and spiritual things. The latter however are so remote from the sense of the letter that such things cannot possibly be seen. This applies to every single celestial or spiritual thing. From this also anyone may recognize how insane it is to desire to inquire into matters of faith through sensory evidence and factual knowledge and to refuse to believe unless one grasps them by that method.
