Ya`akov said to Par`oh, *The days of the years of my pilgrimage are one hundred thirty years. Few and evil have been the days of the years of my life, and they have not attained to the days of the years of the life of my fathers in the days of their pilgrimage.*
For who knows what is good for man in life, all the days of his vain life which he spends like a shadow? For who can tell a man what will be after him under the sun?
