Isaiah 19:18-22

In 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. In 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. It 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. [Judg 2:18; 3:9, 15] And 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. The LORD will strike Egypt, striking but healing it; so they will return to the LORD, and He will respond to them and heal them.
