15 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.
40 They shall also bring up a company against thee, and they shall stone thee with stones, and thrust thee through with their swords.
'Perpetual' in the literal sense, means to the end of one's life, after death, and eternity.
