'Remnant' in the Bible

So the couriers went with the letters from the king and his princes throughout all Israel and Judah, and according to the commandment of the king, saying, "You children of Israel, turn again to Yahweh, the God of Abraham, Isaac, and Israel, that he may return to the remnant that have escaped of you out of the hand of the kings of Assyria.

They came to Hilkiah the high priest, and delivered the money that was brought into the house of God, which the Levites, the keepers of the threshold, had gathered of the hand of Manasseh and Ephraim, and of all the remnant of Israel, and of all Judah and Benjamin, and of the inhabitants of Jerusalem.
