Proverbs 26:23-25

Names of God Bible

²³ Like a clay pot covered with cheap silver,
    so is smooth talk that covers up an evil heart.
²⁴ Whoever is filled with hate disguises it with his speech,
    but inside he holds on to deceit.
²⁵ When he talks charmingly, do not trust him
    because of the seven disgusting things in his heart.
