Sirach 30:8 In-Context

6 He was survived by those who would avenge him against his enemies and who would repay kindness to his friends.

7 A parent who spoils children now will end up tending to their wounds, and will experience heartache at every outcry.

8 A horse that is unbroken turns out stubborn, and a child, when given free rein, turns out reckless.

9 Indulge children, and they will terrorize you; play with them, and they will grieve you.

10 Don't laugh together with them, so that you don't suffer together and in the end grind your teeth in regret.
