Aaron
Aaron was the brother of Moses. He symbolizes two things, at different stages of the story.
During the first part of the exodus, when he was Moses' spokesperson, Moses represents the Word as it truly is, as it is understood in heaven, while Aaron represents the Word in its external sense, as it is understood by people in the world. This is why Aaron talks for Moses, and the Lord says of him "he shall be as a mouth for you, and you shall be to him as God." (Exodus 4:16)
Later, after the Tabernacle was built and he was inaugurated as high priest (see Leviticus 8,9), Aaron represents the Lord as to the Divine Good, and Moses represents the Lord as to the Divine Truth.
In Exodus 28:1, Aaron signifies the conjunction of Divine Good with Divine Truth in the Divine Human of the Lord. (Arcana Coelestia 9806, 9936)
In Exodus 32:1, Aaron represents the external of the Word, of the church, and of worship, separate from the internal. (Arcana Coelestia 10397)
In Exodus 4:14, before he was initiated into the priesthood, Aaron represents the doctrine of good and truth. (Arcana Coelestia 6998)
Isaiah 19:1-17
1
The burden of Egypt: "Behold, Yahweh rides on a swift cloud, and comes to Egypt. The idols of Egypt will tremble at his presence; and the heart of Egypt will melt in its midst.
2
I will stir up the Egyptians against the Egyptians, and they will fight everyone against his brother, and everyone against his neighbor; city against city, and kingdom against kingdom.
3
The spirit of Egypt will fail in its midst. I will destroy its counsel. They will seek the idols, the charmers, those who have familiar spirits, and the wizards.
4
I will give over the Egyptians into the hand of a cruel lord. A fierce king will rule over them," says the Lord, Yahweh of Armies.
5
The waters will fail from the sea, and the river will be wasted and become dry.
6
The rivers will become foul. The streams of Egypt will be diminished and dried up. The reeds and flags will wither away.
7
The meadows by the Nile, by the brink of the Nile, and all the sown fields of the Nile, will become dry, be driven away, and be no more.
8
The fishermen will lament, and all those who fish in the Nile will mourn, and those who spread nets on the waters will languish.
9
Moreover those who work in combed flax, and those who weave white cloth, will be confounded.
10
The pillars will be broken in pieces. All those who work for hire will be grieved in soul.
11
The princes of Zoan are utterly foolish. The counsel of the wisest counselors of Pharaoh has become stupid. How do you say to Pharaoh, "I am the son of the wise, the son of ancient kings?"
12
Where then are your wise men? Let them tell you now; and let them know what Yahweh of Armies has purposed concerning Egypt.
13
The princes of Zoan have become fools. The princes of Memphis are deceived. They have caused Egypt to go astray, who are the cornerstone of her tribes.
14
Yahweh has mixed a spirit of perverseness in the midst of her; and they have caused Egypt to go astray in all of its works, like a drunken man staggers in his vomit.
15
Neither shall there be for Egypt any work, which head or tail, palm branch or rush, may do.
16
In that day the Egyptians will be like women. They will tremble and fear because of the shaking of the hand of Yahweh of Armies, which he shakes over them.
17
The land of Judah will become a terror to Egypt. Everyone to whom mention is made of it will be afraid, because of the plans of Yahweh of Armies, which he determines against it.
