Sirach 33:25-27

New Revised Standard Version Catholic Edition

²⁵ Fodder and a stick and burdens for a donkey;
    bread and discipline and work for a slave.
²⁶ Set your slave to work, and you will find rest;
    leave his hands idle, and he will seek liberty.
²⁷ Yoke and thong will bow the neck,
    and for a wicked slave there are racks and tortures.
