Isaiah 19:18-22

In that day five cities in Egypt will speak the language of Canaan and swear allegiance to the LORD Almighty. One of them will be called the City of the Sun. In that day there will be an altar to the LORD in the heart of Egypt, and a monument to the LORD at its border. It will be a sign and witness to the LORD Almighty in the land of Egypt. When they cry out to the LORD because of their oppressors, he will send them a savior and defender, and he will rescue them. So the LORD will make himself known to the Egyptians, and in that day they will acknowledge the LORD. They will worship with sacrifices and grain offerings; they will make vows to the LORD and keep them. The LORD will strike Egypt with a plague; he will strike them and heal them. They will turn to the LORD, and he will respond to their pleas and heal them.
