Sirach 30:8-10

Common English Bible

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.
