ECC:

“Do not be overly righteous,

Nor be overly wise,

Lest you be confounded.

The words of the wise are heard in quietness

More than the shouting of those who rule in foolishness.

Do not curse the king, even in your conscience;

Do not curse the rich, even in your bedroom;

For a bird of the air will carry your voice,

And a bird in flight will tell the matter.

The words of the wise are like pointed sticks, like nails firmly fastened; they are given from the collections and abound from them by one Shepherd.”
