Isaiah 19:19-21

New Century Version

¹⁹ At that time there will be an altar for the Lord in the middle of Egypt and a monument to the Lord at the border of Egypt. ²⁰ This will be a sign and a witness to the Lord All-Powerful in the land of Egypt. When the people cry to the Lord for help, he will send someone to save and defend them. He will rescue them from those who hurt them.

²¹ So the Lord will show himself to the Egyptians, and then they will know he is the Lord. They will worship God and offer many sacrifices. They will make promises to the Lord and will keep them.
