Proverbs 26:25-27

Revised Standard Version Catholic Edition

²⁵ when he speaks graciously, believe him not,
    for there are seven abominations in his heart;
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.
