parsha bit: Sh'mini

Moshe and Aharon once walked along, with Nadav and Avihu behind them, and all Israel following in the rear. Then Nadav said to Avihu: "Oh that these old men might die, so that you and I should be the leaders of our generation". But the Holy One, blessed be He, said unto them: "We shall see who will bury whom". Rav Papa said: "Thus men say: Many an old camel is laden with the hides of younger ones". (Sanhedrin 52a)
