Sirach 30:9

⁷He that maketh too much of his son shall bind up his wounds; and his bowels will be troubled at every cry.

⁸An horse not broken becometh headstrong: and a child left to himself will be wilful.

— Sirach 30:9 —

¹⁰Laugh not with him, lest thou have sorrow with him, and lest thou gnash thy teeth in the end.

¹¹Give him no liberty in his youth, and wink not at his follies.
