Ben Sira 30:8

8 A horse that is untamed turns out to be stubborn, and a son unrestrained turns out to be wilful.

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 He who spoils his son will bind up his wounds, and his feelings will be troubled at every cry.
8 A horse that is untamed turns out to be stubborn, and a son unrestrained turns out to be wilful.
9 Pamper a child, and he will frighten you; play with him, and he will give you grief.
10 Do not laugh with him, lest you have sorrow with him, and in the end you will gnash your teeth.
