Sirach 30:11-13

Revised Standard Version

¹¹ Give him no authority in his youth,
    and do not ignore his errors.
¹² Bow down his neck in his youth,^[a]
    and beat his sides while he is young,
lest he become stubborn and disobey you,
    and you have sorrow of soul from him.^[b]
13 Discipline your son and take pains with him,
    that you may not be offended by his shamelessness.
