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?
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?
In the day of prosperity be joyful, but in the day of adversity take note that God also has set the one over against the other, to the end that man should find nothing after him.
For all this I took to heart, even to make all this clear, that the righteous and the wise and their works are in the hand of God. No man knows either love or hatred by all that is before them.
