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.
5:16 This is another misfortune:
Just as he came, so will he go.
What did he gain from toiling for the wind?
10:14 yet a fool keeps on babbling.
No one knows what will happen;
who can tell him what will happen in the future?
