Proverbs 26:23-28

23Like the glaze covering an earthen vessel are fervent lips with an evil heart.

24Whoever hates disguises himself with his lips and harbors deceit in his heart;

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

26though his hatred be covered with deception, his wickedness will be exposed in the assembly.

27Whoever digs a pit will fall into it, and a stone will come back on him who starts it rolling.

28A lying tongue hates its victims, and a flattering mouth works ruin.
