Isaiah 19:20-22

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 1Savior and a 23Champion, and He will deliver them. 21Thus the Lord will make Himself known to Egypt, and the Egyptians will know the Lord in that day. They will even worship with 4sacrifice and offering, and will make a vow to the Lord and perform it. 22The Lord will strike Egypt, striking but 5healing; so they will 6return to the Lord, and He will respond to them and will heal them.
