for he does not know that which shall be; nor when it shall be. Who will teach it to him?
For who knows what is good for man in this life, all the days of the life of his vanity which he causes to be as a shadow? for who shall teach the man what shall be after him under the sun?
The fool multiplies words and says, Man cannot tell what shall be, and what shall be after him, who can tell him?
Therefore I perceive that there is nothing better than that a man should rejoice in his own works; for that is his portion; for who shall bring him to see what shall be after him?
In the day of good enjoy that which is good, but in the day of adversity open your eyes and learn: God also has made the one (the day of adversity) before the other, to the end that man should find nothing after him.
There is no remembrance of former things; neither shall there be any remembrance of things that are to come with those that shall come after.
