Isaiah 19: 19: In that day shall there be an altar to the LORD in the midst of the land of Egypt, and a pillar at the border thereof to the LORD.
The Great Pyramid built by the prophet Enoch is spoken of in Isaiah. Referred to as an altar and a pillar, its location in Egypt is described precisely. Ancient Egypt consisted of Lower Egypt and Upper Egypt, and the Great Pyramid is located between the two, thus it is in the midst of the land of Egypt. Furthermore, because the Great Pyramid sits between Upper Egypt and Lower Egypt, it is thus on their border.
