Proverbs 26:27

²⁵ When he speaks graciously, do not believe him, for seven abominations fill his heart.

²⁶ Though his hatred is concealed by deception, his wickedness will be exposed in the assembly.

He who digs a pit will fall into it, and he who rolls a stone will have it roll back on him.

²⁸ A lying tongue hates those it crushes, and a flattering mouth causes ruin.

Do read the surrounding verses too, because the context often says more than a single verse.
