'Remnant of Jacob' in the Bible

The remnant shall return, even the remnant of Jacob, unto the mighty God.

And the remnant of Jacob shall be in the midst of many people as a dew from the LORD, as the showers upon the grass, that tarrieth not for man, nor waiteth for the sons of men.

And the remnant of Jacob shall be among the Gentiles in the midst of many people as a lion among the beasts of the forest, as a young lion among the flocks of sheep: who, if he go through, both treadeth down, and teareth in pieces, and none can deliver.
