Proverbs 26:23-25

Complete Jewish Bible

²³ Like silver slag overlaid on a clay pot
    are lips that burn [with friendship] over a hating heart.
²⁴ He who hates may hide it with his speech;
    but inside, he harbors deceit.
²⁵ He may speak pleasantly, but don’t trust him;
    for seven abominations are in his heart.
