“On that day,
There will be an altar to Yahweh
In the center of the land of Egypt.
There will be a pillar to Yahweh
At its border.
It will be a sign.
It will be a witness
To Yahweh of hosts
In the land of Egypt.
When they cry to Yahweh
Because of oppressors,
He will send them a savior.
He will defend them.
He will deliver them.
Yahweh will make himself known
To the Egyptians.
The Egyptians will know Yahweh.
On that day,
They will worship with sacrifice.
They will worship with burnt offering.
They will make vows to Yahweh.
They will perform them.
Yahweh will strike Egypt,
Striking and healing.
They will return to Yahweh.
He will listen to their supplications.
He will heal them.”
On that special day, the Egyptians will convert to Yahweh. They will build an altar to Yahweh in the center of Egypt, much like another Jerusalem. There will even be a pillar to Yahweh at the borders of Egypt. This would indicate and witness that Egypt was under the protection of Yahweh. If they had any oppressors, all that they had to do was to cry out to Yahweh for help. Then he would send a savior to them in order to defend and deliver them. They were also going to be the people of Yahweh as the Egyptians would worship with sacrifices and burnt offerings to Yahweh. They would make vows and perform them for Yahweh. Yahweh would listen to them and heal them. He even would forgive them like the Israelites. Thus we have a new people of Yahweh in Egypt. How different this is from the idea of a few remnant Israelites in Jerusalem.
