For who knows what is good for man in life, all the days of his vain life which he spends as a shadow? For who can tell a man what shall be after him under the sun?
I sought in my heart to drag my flesh with wine, yet leading my heart with wisdom; and to lay hold on folly, until I might see where the good for the sons of men might be, what they should do under the heavens all the days of their life.
Therefore I have seen that there is nothing better than that a man should rejoice in his own works; for that is his portion; for who can bring him to see what shall be after him?
All things I have seen in the days of my vanity; there is a just one who perishes in his righteousness, and there is a wicked one who prolongs life in his wickedness.
Look on life with the wife whom you love all the days of the life of your vanity, which He has given you under the sun, all the days of your vanity. For that is your share in this life, and in your labor which you labor under the sun.
