Yesaya 17:6

17:6 There will be some left behind,

like when an olive tree is beaten –

two or three ripe olives remain toward the very top,

four or five on its fruitful branches,”

says the Lord God of Israel.

Yesaya 65:20

65:20 Never again will one of her infants live just a few days ¹ 

or an old man die before his time. ² 

Indeed, no one will die before the age of a hundred, ³ 

anyone who fails to reach ⁴  the age of a hundred will be considered cursed.

[65:20]  ¹ tn Heb “and there will not be from there again a nursing infant of days,” i.e., one that lives just a few days.

[65:20]  ² tn Heb “or an old [man] who does not fill out his days.”

[65:20]  ³ 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.

[65:20]  ⁴ tn Heb “the one who misses.” חָטָא (khata’) 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.”
