'Remnant' in the Bible
A remnant will come back, a remnant of Jacob, to the mighty God.
For though your people, Israel, are as numerous as the sand on the seashore, only a remnant will come back. Destruction has been decreed; just punishment is about to engulf you.
At that time the sovereign master will again lift his hand to reclaim the remnant of his people from Assyria, Egypt, Pathros, Cush, Elam, Shinar, Hamath, and the seacoasts.
There will be a highway leading out of Assyria for the remnant of his people, just as there was for Israel, when they went up from the land of Egypt.
At that time the Lord who commands armies will become a beautiful crown and a splendid diadem for the remnant of his people.
Perhaps the Lord your God will hear all these things the chief adviser has spoken on behalf of his master, the king of Assyria, who sent him to taunt the living God. When the Lord your God hears, perhaps he will punish him for the things he has said. So pray for this remnant that remains.'"
"For a remnant will leave Jerusalem; survivors will come out of Mount Zion. The intense devotion of the Lord who commands armies will accomplish this.
he says, "Is it too insignificant a task for you to be my servant, to reestablish the tribes of Jacob, and restore the remnant of Israel? I will make you a light to the nations, so you can bring my deliverance to the remote regions of the earth."
