Proverbs 26:23-28

Fervent lips with a wicked heart Are like earthenware covered with silver dross. He who hates, disguises it with his lips, And lays up deceit within himself; When he speaks kindly, do not believe him, For there are seven abominations in his heart; Though his hatred is covered by deceit, His wickedness will be revealed before the assembly. Whoever digs a pit will fall into it, And he who rolls a stone will have it roll back on him. A lying tongue hates those who are crushed by it, And a flattering mouth works ruin.
