Why was Aten worship so important even in Amenhotep III's reign?
Why was Amenhotep III's high priest at Heliopolis, Egypt so important?
Amenhotep III gave rebirth to solar sun-god Aton worship because Joshua was at war with the Amorites, and the sun stood still in the midst of heaven and did not go down about a whole day. (Joshua 10:12-14) There was no day like this before or after.
This must have caused panic among the Egyptians. First, there was Moses and the 10 plagues and now there is Joshua's request that the sun shine until the Hebrews defeated all their enemies.
Is it any wonder why Akhenaten sent no troops to Canaanite kings requesting help? Mitanni king Tushratta even had a military alliance with Akhenaten and sent no Egyptian troops to help Tushratta in his war against the Hittites.
The Bible reveals from the Exodus to Rehoboam's 4th year, some 520 years later, the Egyptians did not attack. It was the 521st year after the Exodus in Rehoboam's 5th year Shishak attacked Jerusalem. (1 Kings 14:25)
Shishak was Egypt's first king of Libyan origin. The Egyptian kings had to have heard the stories about Moses and Joshua, since they stayed away from Israel all during the Book of Judges and stayed away in the reigns of king Saul, king David and king Solomon.
