Sir 30:10
King James Version
“Laugh not with him, lest thou have sorrow with him, and lest thou gnash thy teeth in the end.”
Context
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.
9Cocker thy child, and he shall make thee afraid: play with him, and he will bring thee to heaviness.
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.
12Bow down his neck while he is young, and beat him on the sides while he is a child, lest he wax stubborn, and be disobedient unto thee, and so bring sorrow to thine heart.
13Chastise thy son, and hold him to labour, lest his lewd behaviour be an offence unto thee.
