Sirach 22:7 CPDV

⁵  She who is bold shames her father and her husband, and she will not be less offensive to the impious. For she will be held in dishonor by both.

⁶  An untimely explanation is like music in a time of mourning. But the sharp correction and doctrine of wisdom are ever timely.

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?'
