시편 90:10 탈무드 참조: Jerusalem Talmud Bikkurim & Chagigah

From where do you understand that if somebody dies at age 50, he dies of extirpation? It is written (Num. 4:18–19): “Do not extirpate the tribe of the families of (Levi), etc. Do the following for them that they should live and not die.” Organize them that they should not enjoy seeing the holiest of holies. And it is written (Num. 4:20): “They should not come to look, when the holies are wrapped, and die.” And it is written (Num. 8:25): “At age 50, he should retire from the work force.” Rebbi Abin, the son of Rebbi Tanḥum ben Rebbi Tryphon, understood it from here (Ps. 90:10): “The days of our lives here are 70 years.” Subtract from these 20 years during which the Heavenly Court does neither punish not extirpate¹³This tradition is also in the Babli, Šabbat 89b. While a male becomes a full member of the religious community at age 13, a female at age 12, they are treated as adults before the Heavenly court only at age 20 since in the story of the spies only the men older than 20 were punished. One has to assume that until then the parents are not absolved from responsibility for their children.
Neither “proof” has any logical consistency., and you will find that one who dies at up to 50 years dies in extirpation.

At 70, a death of love. (Ps. 90:10): “The days of our lives are then 70 years.” At 80, death of old age, as it is said: “At most, 80 years.” Also thus Barzilai²⁰In verse 33, he is described as “extremely old, 80 years of age.” said to David (2S. 19:36): “I am today 80 years of age, do I still know good from bad?”

How many are the [average] days of a man? Seventy years, as it is said, "The days of our life in it are seventy years, and if with strength, eighty years (Psalms 90:10)." Behold! The distance from the earth to the firmament a five-hundred years' walk! And the thickness of every firmament is a five-hundred years' walk, and so too between every firmament!
