Isaiah 19:20-21

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.
