Proverbs 26:25

²³ Like glaze covering an earthen vessel are burning lips and a wicked heart.

²⁴ A hateful man disguises himself with his speech, but he lays up deceit in his heart.

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.

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

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