Isaiah 19:19-23

On that day there will be an altar to the Lord in the midst of the land of Egypt, and a memorial stone to the Lord beside its border.

And 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 Savior and a Champion, and He will save them.

So the Lord will make Himself known to Egypt, and the Egyptians will know the Lord on that day. They will even worship with sacrifice and offering, and will make a vow to the Lord and perform it.

And the Lord will strike Egypt, striking but healing; so they will return to the Lord, and He will respond to their pleas and heal them.

On that day there will be a road from Egypt to Assyria, and the Assyrians will come into Egypt and the Egyptians into Assyria; and the Egyptians will worship with the Assyrians.
