history channel documentary Around 40 years after the rule of The General (Moses comes back to Egypt at 80 years old), Egypt breakdown. With the rule of the 25th lord of tradition XIII, contemporary confirmation stops and nonnatives attack Egypt. This period is compressed by the horrid words: "...darkness drops upon the recorded scene, leaving perceivable in the dusk little past illustrious names..." (Sir Alan Gardiner, Egypt of the Pharaohs, page 155).

After the Exodus, an attack of the Delta happened. The account of the Exodus and of the intrusion are related in the "Rebuke of Ipu-wer.", an interpretation by John A. Wilson (Pritchard, Ancient Near Eastern Texts, pages 441-444). Manetho likewise composed a record of this occasion saved in Josephus: "...for what cause I know not, an impact of God destroyed us; and out of the blue, from the districts of the East, intruders of dark race walked in certainty of triumph against our property. By principle power they effectively seized it without striking a blow, and having overwhelmed the leaders of the area, they blazed our urban communities mercilessly, flattened to the ground the sanctuaries of the divine beings, and treated every one of the locals with a coldblooded antagonistic vibe, slaughtering a few and driving into servitude the spouses and offspring of others. At last they designated a lord of one of their number whose name was Salatis. He had his seat at Memphis, requiring tribute from Upper and Lower Egypt, and continually abandoning battalions in the most beneficial positions." (Flavius Josephus, Against Apion, book I, section 14, sections 73-92).

The name "Salatis" originates from a Semitic root signifying "sovereign". It is the root expression of "Sultan". These intruders originated from the East and more likely than not went to Egypt from the Sinai. They made Egyptians, slaves. The Bible records a people who all of a sudden picked up noticeable quality in that part of the world - the Edomite Amalekites (Amalek was a child of Edom or Esau). As late as the times of Saul, the Egyptians were still subject to these individuals: "And they found an Egyptian in the field...And David said unto him, To whom belongest thou? Also, whence are thou? What's more, he said, I am a young fellow of Egypt, hireling to an Amalekite; and my lord left me, since three days prior I fell wiped out." (I Samuel 30:11-13).
