NET
20 Never again will one of her infants live just a few days or an old man die before his time. Indeed, no one will die before the age of one hundred; anyone who fails to reach the age of one hundred will be considered cursed.
Darby
20 There shall be no more thenceforth an infant of days, nor an old man that hath not completed his days; for the youth shall die a hundred years old, and the sinner being a hundred years old shall be accursed.
KJV
20 There shall be no more thence an infant of days, nor an old man that hath not filled his days: for the child shall die an hundred years old; but the sinner [being] an hundred years old shall be accursed.
