'Remnant' in the Bible

It may be that the Lord your God will hear all the words of the Rabshakeh, whom his master the king of Assyria has sent to taunt and defy the living God, and will rebuke the words which the Lord your God has heard. So offer a prayer for the remnant [of His people] that is left [in Judah].’”

The survivors who remain of the house of Judah will again take root downward and bear fruit upward.

For a remnant will go forth from Jerusalem, and [a band of] survivors from Mount Zion. The zeal of the Lord of hosts shall perform this.
