Ben Sira 30:8

8 An untamed horse is going to be stubborn, and an undisciplined son is no different.

Ben Sira 30:8 In-Context

6 He has left someone to take vengeance on his enemies and to return the favors he owes his friends.
7 But anyone who spoils his son will have to bandage his wounds. His heart will stop every time he hears a shout.
8 An untamed horse is going to be stubborn, and an undisciplined son is no different.
9 If you pamper your child and play with him, he will be a disappointment and a source of grief.
10 Laugh with him now, and one day you will have to cry over him, grinding your teeth in regret.
