Ecclesiastes 8:7

7 For he knoweth not that which shall be, for when it shall be who declareth to him?

Ecclesiastes 8:15

15 And I have praised mirth because there is no good to man under the sun except to eat and to drink, and to rejoice, and it remaineth with him of his labour the days of his life that God hath given to him under the sun.

Ecclesiastes 8:17

17 then I considered all the work of God, that man is not able to find out the work that hath been done under the sun, because though man labour to seek, yet he doth not find; and even though the wise man speak of knowing he is not able to find.
