The sword is without, and the pestilence and the famine within: he that is in the field shall die with the sword; and he that is in the city, famine and pestilence shall devour him.
The sword is without, and the pestilence and the famine within - no security from death should anywhere be found (Deuteronomy 32:25). Fulfilled in the destruction of Jerusalem by Nebuchadnezzar (Lamentations 1:20). He that is in the field shall die with the sword; and he that is in the city, famine ... shall devour him. So Christ warns prophetically as to the Roman invasion (Matthew 24:16-18).
