Ecclesiastes 8:16-17

16 When I gave my heart to know wisdom and to see the task which has been done on the earth (even though one should never sleep day or night ),

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.

Ecclesiastes 9:1

1 For I have taken all this to my heart and explain it that righteous men, wise men, and their deeds are in the hand of God. Man does not know whether it will be love or hatred; anything awaits him.

Ecclesiastes 11:5

5 Just as you do not know the path of the wind and how bones are formed in the womb of the pregnant woman, so you do not know the activity of God who makes all things.
