Isaiah 19:20-22

20And it will become a sign and a witness to the Lord of armies in the land of Egypt; for they will cry out to the Lord because of oppressors, and He will send them a 1Savior and a 2Champion, and He will save them. 21So the Lord will make Himself known to Egypt, and the Egyptians will know the Lord on that day. They will even worship with 3sacrifice and offering, and will make a vow to the Lord and perform it. 22And the Lord will strike Egypt, striking but 4healing; so they will 5return to the Lord, and He will respond to their pleas and heal them.
