Sirach 27:25-27

New Revised Standard Version, Anglicised Catholic Edition

²⁵ Whoever throws a stone straight up throws it on his own head,
    and a treacherous blow opens up many wounds.
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.
