ביטוי (אנגלית)

Many Old Camels Are Marked in the Hides of Young Calves/ many young men die before the old

הגדרה (אנגלית)

By metaphor: young age does not guarantee longevity (see also: "Many travelers died and their hides were spread flat on the backs of their camels").

("Nadab said to his father: My father, when the two old men had died, and you and I would lead the generation? The Holy One, blessed be He, said to him: Let us see who will bury me. Rav Papa said: These are the words of my people: my soul, my grandfather's camels, my grain, my donkey's bedding" - Sanhedrin Nov. 1)
