Isaiah 19:19-21 New American Standard Bible (NASB)
19 On that day there will be an altar to the Lord in the midst of the land of Egypt, and a memorial stone to the Lord beside its border.
20 And it will become a sign and a witness to the Lord of armies in the land of Egypt; for they will cry out to the Lord because of oppressors, and He will send them a Savior and a Champion, and He will save them.
21 So the Lord will make Himself known to Egypt, and the Egyptians will know the Lord on that day. They will even worship with sacrifice and offering, and will make a vow to the Lord and perform it.
Only Egypt has a location that’s both on the border and in the heart of the country. That’s possible because in Hebrew, Egypt’s name is Mizraim, a plural word that means “two Egypts.” In ancient times they were two countries, Upper (southern) Egypt and Lower (northern) Egypt, but they were joined to become one.
The name of this location is Giza. It’s on the border between the two Egypts and in the heart of the combined Egypt. And there’s already a one-of-a-kind ancient monument there, called the Great Pyramid.

Thats quite interesting. I’ve never heard of that connection begore nor of that Scripture.
I wonder if the following ties into that. (The Covenent made with Abraham)
Genesis 15:
18 In the same day the Lord made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates:
19 The Kenites, and the Kenizzites, and the Kadmonites,
20 And the Hittites, and the Perizzites, and the Rephaims,
21 And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.
And only the ignorant claim the children of Israel built the pyramids.
Giza is clearly in Lower Egypt
Furthermore note:
they are not in the same place
Furthermore So the Lord will make Himself known to Egypt, and the Egyptians will know the Lord on that day. They will even worship with sacrifice and offering, and will make a vow to the Lord and perform it. -- this WAS FULFILLED by 200 AD -- Egypt was the CENTER of Christian belief and learning, along with Ctesiphon (now adjacent to Baghdad) from 200 AD to about 600 AD
The Egyptians were 100% Christian by the time of the Islamic invasions.
Egypt only became majority Muslim in the 13th century
