The name “Moses” is Egyptian and it means “son of” and we find it in names of Egyptian pharaohs like Rameses and Tutmoses. Moses was a renegade prince,who fled Egypt after killing a supervisor of Jewish laborors. They worked as slaves on the city of Piramses, build by Ramses II, the Great. He escaped the wrath of the pharaoh and went to the country of “Midjan” (across the “Gulf of Eilat or the “Arig al-Aqaba” in, now, Saudi-Arabia).
After Jaweh presents himself to Moses, he returns to liberate his people (the Jews). They lived in the North of the delta for a few generations, after fleeing Kanaan because of a draught. Josef welcomed them and gave his tribe access to the wealth of the country along the Nile. After Jozef's death and changes in Egypt's leadership the hospitality faded and the Jews worked as slave-laborers to build the new capital of Ramses II. This places the Exodus, according to historians, around 1200 BC.
Some say that the Jews were kicked out of Egypt, because the local people envied their wealth and feared their secluviness. Next the fleeing Jews are saved from the forces of the Pharaoh, because the waters of the Red Sea part and the Jews escape. The charriots of Ramses disappear into the returning waters, killing most of the soldiers.
But is this correct (geographical)? First it seems quite illogical, that the future Israelites crossed the Red Sea. They lived in the North and they had to leave Egyptian territory, by following the route Moses knew, the road to Midjan (Midian), that led out of the pharaonic Empire. That would also explain, the signs the fugitives saw. Clouds/smoke during daytime and fire at night, that showed the way. According to Ron Wyatt (Biblical archeologist) the Jews marched towards the “Gabal al-Laur”, an active volcano. In Saudi-Arabia. The parting of the sea took place in the “Gulf of Eilat”, before they reached the safety of Midjan.
But why did Ramses send his elite-soldiers after the Jews. The story goes, that Moses stole an ancient piece of technology, that belonged to the Egyptian rulers. With this technology Moses was able to part the Harig al-Aqaba and “closing” the waters, when the Egyptian army followed the Jews into Midlan. Ron Wyatt had unearthed a number of wheels and bronze ornaments, belonging to Egyptian charriots. Ramses was defeated and after Moses received the Ten Commandments, they went North on their journey of 40 years to the Holy Land. You ask: “What happened to the mysterious weapon, Moses stole?” Moses had made a special box for this “wonder-weapon” and he called it “the Ark of the Covenant”.
