Proverbs 26:25-27 Revised Standard Version Catholic Edition (RSVCE)
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.
