Talmud su Numeri 4:18

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.
