“Or if I send a pestilence into that land, and pour out my fury on it in blood, to cut off from it man and beast, though Noah, Daniel and Job were in it, as I live says the Lord Yahweh, they will deliver neither son nor daughter. They will deliver but their own lives by their righteousness.”
The same principle applies when God determines to bring pestilence on a land in His anger against sin and idolatry, the presence of the truly righteous would not save the land, nor even their own families. Only the righteous themselves would be delivered.
