Isaiah 19:20-21

It will be a sign and a witness that the LORD of Heaven’s Armies is worshiped in the land of Egypt. When the people cry to the LORD for help against those who oppress them, he will send them a savior who will rescue them. The LORD will make himself known to the Egyptians. Yes, they will know the LORD and will give their sacrifices and offerings to him. They will make a vow to the LORD and will keep it.
