Could "polluted persons" refer to those whose "mother blood" had been corrupted by their mixing with the Asiatic Hyksos?

"Under a king of ours named Timaus (Tutimaeus) God became angry with us, I know not how, and there came, after a surprising manner, men of obscure birth from the east, and had the temerity to invade our country, and easily conquered it by force, as we did not do battle against them. After they had subdued our rulers, they burnt down our cities, and destroyed the temples of the gods, and treated the inhabitants most cruelly; killing some and enslaving their wives and their children.
Then they made one of their own king. His name was Salatis [1]; he lived at Memphis, and both the upper and lower regions had to pay tribute to him. He installed garrisons in places that were the most suited for them. His main aim was to make the eastern parts safe, expecting the Assyrians, at the height of their power, to covet his kingdom, and invade it. In the Saite Nome there was a city very proper for this purpose, by the Bubastic arm of the Nile. With regard to a certain theologic notion it was called Avaris. He rebuilt and strengthened this city by surrounding it with walls. and by stationing a large garrison of two hundred and forty thousand armed men there. Salitis came there in the summer, to gather corn in order to pay his soldiers, and to exercise his men, and thus to terrify foreigners. After a reign of thirteen years, he was followed by one whose name was Beon [2], who ruled for for forty-four years. After him reigned Apachnas [3] for thirty-six years and seven months. After him Apophis [4] was king for sixty-one years, followed by Janins for fifty years and one month. After all these Assis reigned during forty-nine years and two months.
These six were their first kings. They all along waged war against the Egyptians, and wanted to destroy them to the very roots."

King Amenophis/Amonhotep did not retreat to the Levant, Arabia, Asia nor Greece to strengthen is forces, he retreated to Kush for replenishment. This alone speaks volumes about the relationship between Kemet and Kush. The King knew he could not trust his half-caste subjects in the North.

It was these half-breeds that were sent to work in the quarries, once their progenitors the Hyksos were expunged from Kemetian land. It was from this population of half-breeds that Moses arose.

Approaching it from this view point we understand why so much of Hebrew history seem to be taken right out of the pages of Kemetian history and we also gain insight into the phyche of the Hebrew.

In hindsight, Kemet would have been better served, if King Amenophis had expelled the half-caste along with their progenitors.
