Ben Sira 30:8

8 An unbroken horse turns out stubborn, and an unchecked son turns out headstrong.

Ben Sira 30:8 In-Context

6 He has left behind him an avenger against his enemies, and one to repay the kindness of his friends.

7 Whoever spoils his son will bind up his wounds, and will suffer heartache at every cry.

8 An unbroken horse turns out stubborn, and an unchecked son turns out headstrong.

9 Pamper a child, and he will terrorize you; play with him, and he will grieve you.

10 Do not laugh with him, or you will have sorrow with him, and in the end you will gnash your teeth.
