Sirach 20:29-31

Common English Bible

²⁹ Friendly relationships and gifts
will blind the eyes of the wise;
    like a muzzle on a mouth,
    they turn away reproof.
³⁰ Hidden wisdom and unseen treasure—
    of what benefit is either?
³¹ Better are those who hide
their foolishness
    than those who hide their wisdom.^[a]
