Isaiah 19:18-22

18In that day five cities in the land of Egypt will speak the language of [the Hebrews of] Canaan and swear allegiance to the Lord of hosts. One [of them] will be called the City of Destruction.

19In that day there will be an altar to the Lord in the midst of the land of Egypt, and a memorial stone to the Lord near its border.

20It will become a sign and a witness to the Lord of hosts in the land of Egypt; for they will cry to the Lord because of oppressors, and He will send them a Savior, a [Great] Defender, and He will rescue them.

21And so the Lord will make Himself known to Egypt, and the Egyptians will know [heed, honor, and cherish] the Lord in that day. They will even worship with sacrifices [of animals] and offerings [of produce]; they will make a vow to the Lord and fulfill it.

22The Lord will strike Egypt, striking but healing it; so they will return to the Lord, and He will respond to them and heal them.
