1 In the 10th year, in the 10th month, in the 12th day of the month, the word of Yahweh came unto me, saying,

2 Son of man, set thy face against Pharaoh king of Egypt, and prophesy against him, and against all Egypt:

Chapters 29-32 contain the judgments on Egypt. These prophecies began in the tenth year, about the time Hophra, king of Egypt, was marching to the relief of Israel. He forced Nebuchadnezzar to raise the siege of Jerusalem, but was soon driven back to Egypt and did not try again.

After two thousand previous years of prominent world power, Egypt should become a base nation, and not lift itself again.

Bro Growcott - Prophecies in the captivity

3 Speak, and say, Thus saith the Adonai Yahweh; Behold [Hineni], I am against thee, Pharaoh king of Egypt [Melech Mitzrayim], the great dragon [monster] that lieth in the midst of his rivers, which hath said, My river [Nile] is mine own, and I have made it for myself.

A dragon is a kind of beast, and therefore partakes in the characteristics of beasts. These in prophetic writing are the well-known symbols of destroying monarchies or powers; and, where the people of the Deity are found sojourning under their authority, the persecutors of the saints...

...The Hebrew tannin, and the Greek drakon, rendered in our English version dragon, it is evident from Ezek. 29:3, signifies a crocodile; the great scaly serpent-fish of the Nile, the symbol of the Egyptian power styled "Pharaoh king of Egypt, the great dragon that lieth in the midst of his rivers."

The dragon, then, whose force is in his tail, symbolized the power of the old Egyptian Polity. This, in the days of Moses, was the great enemy of Israel after both flesh and spirit. It embodied in its institutions all the filthiness, and superstition, and tyranny of human nature; and stood before the world as the great SIN-POWER of antiquity - "the Old Serpent, the Devil and the Satan."

..."The Dragon," says Daubuz, "is a crocodile, a creature which is ranked among the serpents by Horus Apollo; and is called by the Arabians Pharaoh, and which was held by the Egyptians as the symbol of all mischief. And therefore Typho being, in their belief, the author of all evil, was supposed to have transformed himself into a crocodile, or dragon.

So that the principle of all evil, or Typho, was in the symbolical character represented by a crocodile or dragon; and under this symbol was the said principle worshipped. Agreeably whereunto in the Chaldean theology the principle of evil was called Arimanius; that is, the crafty serpent, from 'aruwm, crafty, and nachash, serpent. "
