'Remnant' in the Bible

“Yet I will leave a remnant when you are scattered among the nations, for throughout the countries there will be some of you who will escape the sword.

While they were killing, I was left alone. And I fell facedown and cried out, “Oh, Lord God! Are You going to destroy the entire remnant of Israel when You pour out Your wrath on Jerusalem?”

Now while I was prophesying, Pelatiah son of Benaiah died. Then I fell facedown and cried out with a loud voice: “Oh, Lord God! Will You bring to an end the remnant of Israel?”
