Ben Sira 28:20

20 for its yoke is a yoke of iron, and its fetters are fetters of bronze;

Ben Sira 28:20 In-Context

18 Many have fallen by the edge of the sword, but not so many as have fallen because of the tongue.
19 Happy is the man who is protected from it, who has not been exposed to its anger, who has not borne its yoke, and has not been bound with its fetters;
20 for its yoke is a yoke of iron, and its fetters are fetters of bronze;
21 its death is an evil death, and Hades is preferable to it.
22 It will not be master over the godly, and they will not be burned in its flame.
