Arcana Coelestia #52
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.

Numbers 21:27-30
27
Therefore those who speak in proverbs say, "Come to Heshbon. Let the city of Sihon be built and established;
28
for a fire has gone out of Heshbon, a flame from the city of Sihon. It has devoured Ar of Moab, The lords of the high places of the Arnon.
29
Woe to you, Moab! You are undone, people of Chemosh! He has given his sons as fugitives, and his daughters into captivity, to Sihon king of the Amorites.
30
We have shot at them. Heshbon has perished even to Dibon. We have laid waste even to Nophah, Which reaches to Medeba."
