Proverbs 26:26-28

Revised Standard Version Catholic Edition

²⁶ though his hatred be covered with guile,
    his wickedness will be exposed in the assembly.
²⁷ He who digs a pit will fall into it,
    and a stone will come back upon him who starts it rolling.
²⁸ A lying tongue hates its victims,
    and a flattering mouth works ruin.
