Jacob said to Pharaoh, The days of the years of my pilgrimage are 130 years; few and evil have the days of the years of my life been, and they have not attained to those of the life of my fathers in their pilgrimage.
For who [limited to human wisdom] knows what is good for man in his life, all the days of his vain life which he spends as a shadow [going through the motions but accomplishing nothing]? For who can tell a man what will happen [to his work, his treasure, his plans] under the sun after he is gone?
