Isa 65:20 | NET2full | STEP | 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 .

‏ Isaiah 65:20

20 Never again will one of her infants live just a few days ^{▼▼tn Heb “and there will not be from there again a nursing infant of days,” i.e., one that lives just a few days.}
or an old man die before his time. ^{▼▼tn Heb “or an old [man] who does not fill out his days.”}
Indeed, no one will die before the age of one hundred; ^{▼▼tn Heb “for the child as a son of one hundred years will die.” The point seems to be that those who die at the age of a hundred will be considered children, for the average life span will be much longer than that. The category “child” will be redefined in light of the expanded life spans that will characterize this new era.}
anyone who fails to reach ^{▼▼tn Heb “the one who misses.” חָטָא (khataʾ) is used here in its basic sense of “miss the mark.” See HALOT 305 s.v. חטא. Another option is to translate, “and the sinner who reaches the age of a hundred will be cursed.”} the age of one hundred will be considered cursed.
