Ecclesiastes 8:7

7 If no one knows what will happen, who can tell him when it will happen?

Ecclesiastes 8:15

15 So I commended pleasure, for there is nothing good for a man under the sun except to eat and to drink and to be merry, and this will stand by him in his toils throughout the days of his life which God has given him under the sun.

Ecclesiastes 8:17

17 and I saw every work of God, I concluded that man cannot discover the work which has been done under the sun. Even though man should seek laboriously, he will not discover; and though the wise man should say, "I know," he cannot discover.
