2 Kings 19:4

19:4 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.’”

2 Kings 19:31

19:31 For a remnant will leave Jerusalem;

survivors will come out of Mount Zion.

The intense devotion of the sovereign Lord to his people will accomplish this.
