Commento su Giobbe 5:26

You shall come to the grave at a ripe old age Heb. בְכֶלַח. [In other words,] you will be saved from pestilence. As for the word בְכֶלַח: there is no Biblical support to understand its meaning, but according to the context, it can be interpreted as an expression of the completion of the ripening of the grain, when it is completely ripe. Our Rabbis, however, interpret בְכֶלַח as “sixty years,” according to its numerical value.
