Sirach 33:28

28 Set him to work, as is fit for him: if he be not obedient, put on more heavy fetters.

Sirach 33:28 In-Context

26 A yoke and a collar do bow the neck: so are tortures and torments for an evil servant.
27 Send him to labour, that he be not idle; for idleness teacheth much evil.
28 Set him to work, as is fit for him: if he be not obedient, put on more heavy fetters.
29 But be not excessive toward any; and without discretion do nothing.
30 If thou have a servant, let him be unto thee as thyself, because thou hast bought him with a price.
