Proverbs 26:23-25

World English Bible

²³ Like silver dross on an earthen vessel
    are the lips of a fervent one with an evil heart.
²⁴ A malicious man disguises himself with his lips,
    but he harbors evil in his heart.
²⁵ When his speech is charming, don’t believe him,
    for there are seven abominations in his heart.
