תנ״ך אויף קהלת 7:11

For there is no remembrance of the first ones, [i.e., the earlier generations, for which reason the thing seems to be new]; and the later ones, too, who will be [after us], will not be remembered by those who come after them.

For as the sound of the thorns [crackling] under the pot, so is the laughter of the fool [("crackling" with self-importance)]. And this, too, [(the "toil" of contending with the fools)] is a vanity [(relegated to men by G-d)].
