Isaiah 19:18- 20
In that day shall five cities in the land of Egypt speak the language of Canaan, and swear to the LORD of hosts; one shall be called, The city of destruction. 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. And it shall be for a sign and for a witness unto the LORD of hosts in the land of Egypt: for they shall cry unto the LORD because of the oppressors, and he shall send them a saviour, and a great one, and he shall deliver them.
Though Egypt will be disciplined, they will be restored. Five cities will become centers for the worship of Jehovah, including Heliopolis, the city of the Sun, also called the City of Destruction. There will be an altar to the LORD in the midst of the land, and a pillar to the LORD at its border, both of which will be witnesses to the Lord.
