Sirach 27:26-28

Revised Standard Version Catholic Edition

²⁶ He who digs a pit will fall into it,
    and he who sets a snare will be caught in it.
²⁷ If a man does evil, it will roll back upon him,
    and he will not know where it came from.
²⁸ Mockery and abuse issue from the proud man,^[a]
    but vengeance lies in wait for him like a lion.
