Sirach 30:9-11 Catholic Public Domain Version (CPDV)

9. Coddle a son, and he will make you afraid. Play with him, and he will make you sorrowful.

10. You should not laugh with him; otherwise you may have grief, and in the end, your teeth be clenched.

11. You should not give him power in his youth, but you should not despise his thoughts.
