And I have seen that nothing is better than that the man should rejoice in his 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 this life, the number of the days of his life of vanity? Even he makes them like the shadow. For who can tell a man what shall be after him under the sun?
On the good day, be in good spirit, but also consider in the evil day, that God has made this one along with this one, so that man should not find anything after him.
For all this I gave to my heart, even to clear up all this, that the righteous ones and the wise ones and their works are in the hand of God. Also love, also hatred, man does not know all that is before them.
