Proverbs 26:26-28 New Revised Standard Version, Anglicised (NRSVA)
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.
