When they cry out to the Lord because of their oppressors, he will send them a savior and defender, and he will rescue them.

Isaiah 19:1-22

A prophecy against Egypt:

“I will stir up Egyptian against Egyptian— brother will fight against brother, neighbor against neighbor, city against city, kingdom against kingdom. The Egyptians will lose heart,  and I will bring their plans to nothing; they will consult the idols and the spirits of the dead, the mediums and the spiritists. I will hand the Egyptians over to the power of a cruel master, and a fierce king will rule over them,” declares the Lord, the Lord Almighty.

The waters of the river will dry up, and the riverbed will be parched and dry. The canals will stink; the streams of Egypt will dwindle and dry up.

The Lord has poured into them a spirit of dizziness; they make Egypt stagger in all that she does, as a drunkard staggers around in his vomit. There is nothing Egypt can do— head or tail, palm branch or reed.

In that day five cities in Egypt will speak the language of Canaan and swear allegiance to the Lord Almighty. One of them will be called the City of the Sun (Destruction).

In that day there will be an altar to the Lord in the heart of Egypt, and a monument to the Lord at its border. It will be a sign and witness to the Lord Almighty in the land of Egypt. When they cry out to the Lord because of their oppressors, he will send them a savior and defender, and he will rescue them. So the Lord will make himself known to the Egyptians, and in that day they will acknowledge the Lord. They will worship with sacrifices and grain offerings; they will make vows to the Lord and keep them. The Lord will strike Egypt with a plague; he will strike them and heal them. They will turn to the Lord, and he will respond to their pleas and heal them.

Why?

It is possible the Egyptians will worship the Lord one day. Nothing is impossible to our Lord! All is in the hands of the Lord. 

One day when they cry out to the Lord because of their oppressors, so the Lord will strike Egypt with a plague; he will strike them and heal them, and they will turn to the Lord.

How?

Jesus is the Lord he will deliver Egypt from plague and heal them, this Egypt is this world.
