Ecclesiastes 5:12

5:12 The sleep of the laborer is pleasant – whether he eats little or much –

but the wealth of the rich will not allow him to sleep.

Ecclesiastes 5:16

5:16 This is another misfortune:

Just as he came, so will he go.

What did he gain from toiling for the wind?

Ecclesiastes 10:14

10:14 yet a fool keeps on babbling.

No one knows what will happen;

who can tell him what will happen in the future?
