Ecclesiastes 1:18; Ecclesiastes 5:3; Ecclesiastes 5:7; Ecclesiastes 11:1

18 For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

3 For a dream cometh through the multitude of business; and a fool's voice is known by multitude of words.

7 For in the multitude of dreams and many words there are also divers vanities: but fear thou God.

1 Cast thy bread upon the waters: for thou shalt find it after many days.
