Proverbs 26:23-28

23Fervent lips with a wicked heart Are like earthenware covered with silver dross.

24He who hates, disguises it with his lips, And lays up deceit within himself;

25When he speaks kindly, do not believe him, For there are seven abominations in his heart;

26Though his hatred is covered by deceit, His wickedness will be revealed before the assembly.

27Whoever digs a pit will fall into it, And he who rolls a stone will have it roll back on him.

28A lying tongue hates those who are crushed by it, And a flattering mouth works ruin.
