Wisdom of Ben Sira 19:25-27

New Catholic Bible

²⁵ There is a cleverness that is scrupulous but dishonest,
    and there are those who abuse favors to win a favorable decision.
²⁶ There is a wicked man who bows his head in mourning
    but is filled with guile within.
²⁷ He hides his face and pretends not to hear,
    but when no one is paying attention, he will take advantage of you.
