Proverbs 26:25-27

New Revised Standard Version, Anglicised Catholic Edition

²⁵ when an enemy speaks graciously, do not believe it,
    for there are seven abominations concealed within;
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.
