Ecclesiastes 8:7

7 for he does not know that which shall be; nor when it shall be. Who will teach it to him?

Ecclesiastes 8:15

15 Therefore I commended joy because a man has no better thing under the sun than to eat and to drink and to be merry, for that shall abide with him of his labour the days of his life, which God gives him under the sun.

Ecclesiastes 8:17

17 And I have seen regarding all the works of God that man cannot attain to understand the work that is being done under the sun, because though a man labours to seek it out, yet he shall not find it; even though the wise man says that he knows it, yet he shall not be able to attain it.
