Sirach 27:26-28

New Revised Standard Version, Anglicised Catholic Edition

²⁶ Whoever digs a pit will fall into it,
    and whoever sets a snare will be caught in it.
²⁷ If a person 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,
    but vengeance lies in wait for them like a lion.
