Proverbs 26:24–26
24 Whoever hates disguises himself with his lips
and harbors deceit in his heart;
25 vwhen he speaks graciously, believe him not,
for there are wseven abominations in his heart;
26 though his hatred be covered with deception,
his wickedness will be exposed in the assembly.
Proverbs 26:28
28 A lying tongue hates its victims,
and a flattering mouth works ruin.
