Isaiah 19:18-22

18In that day five cities in the land of Egypt will speak the language of Canaan and swear allegiance to the LORD of Hosts. One of them will be called the City of the Sun.1

19In that day there will be an altar to the LORD in the center of the land of Egypt, and a pillar to the LORD near her border. 20It will be a sign and a witness to the LORD of Hosts in the land of Egypt. When they cry out to the LORD because of their oppressors, He will send them a savior and defender to rescue them. 21The LORD will make Himself known to Egypt, and on that day Egypt will acknowledge the LORD. They will worship with sacrifices and offerings; they will make vows to the LORD and fulfill them.

22And the LORD will strike Egypt with a plague; He will strike them but heal them. They will turn to the LORD, and He will hear their prayers and heal them.
