7 Whoever teaches the foolish is like someone who glues together a broken pot.
8 Whoever explains a word to one who is not listening is like someone who suddenly awakens a sleeping person from a deep sleep.
9 Whoever explains wisdom to the senseless is like one speaking to a sleeping person. And at the end of the explanation, he says: "Who is this?"
10 Weep over the dead, for his light has failed. And weep over the foolish, for his understanding has failed.
11 Weep only a little over the dead, for he is at rest.
12 But the wicked life of a wicked fool is worse than death.
13 The mourning for the dead is seven days; but for the foolish and the impious, it is all the days of their life.
