Proverbs 26:26-28

New Revised Standard Version, Anglicised Catholic Edition

²⁶ though hatred is covered with guile,
    the enemy’s wickedness will be exposed in the assembly.
²⁷ Whoever digs a pit will fall into it,
    and a stone will come back on the one who starts it rolling.
²⁸ A lying tongue hates its victims,
    and a flattering mouth works ruin.
