Declare in Egypt, and proclaim in Migdol; proclaim in Memphis and Tahpanhes; say, ‘Stand ready and be prepared, for the sword shall devour around you.’
Jeremiah 46:14

Be watchful and ready for the coming of the Day of the Lord. Be prepared to leave Egypt or be judged with Egypt! I doubt that a bunker will be of much help in either case, but I could be wrong.
