From the book of the prophet Isaiah
The future conversion of Egypt and Assyria
On that day the Egyptians shall be like women, trembling with fear, because of the Lord of hosts shaking his fist at them. And the land of Judah shall be a terror to the Egyptians. Every time they remember Judah, they shall stand in dread because of the plan which the Lord of hosts has in mind for them.
On that day there shall be five cities in the land of Egypt speaking the language of Canaan and swearing by the Lord of hosts; one shall be called “City of the Sun.”
On that day there shall be an altar to the Lord in the land of Egypt, and a sacred pillar to the Lord near the boundary. It shall be a sign and a witness to the Lord of hosts in the land of Egypt, when they cry out to the Lord against their oppressors, and he sends them a savior to defend and deliver them. The Lord shall make himself known to Egypt, and the Egyptians shall know the Lord in that day; they shall offer sacrifices and oblations, and fulfill the vows they make to the Lord. Although the Lord shall smite Egypt severely, he shall heal them; they shall turn to the Lord and he shall be won over and heal them.
On that day there shall be a highway from Egypt to Assyria; the Assyrians shall enter Egypt, and the Egyptians enter Assyria, and Egypt shall serve Assyria.
On that day Israel shall be a third party with Egypt and Assyria, a blessing in the midst of the land, when the Lord of hosts blesses it: “Blessed be my people Egypt, and the work of my hands Assyria, and my inheritance, Israel.”
