If you your lips would keep from slips, Five things observe with care:
Of whom you speak, to whom you speak,
And how and when and where.

If you your ears would save from jeers, These things keep meekly hid:
Myself and I, and mine and my
And how I do and did.

A wise old owl lived in an oak;
The more he saw the less he spoke;
The less he spoke the more he heard:
Why can't we all be like that bird?
  — Edward Hersey Richards

If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.

The tongue is a little member, and boasteth great things. Behold, how great a matter a little fire kindleth!

Who is a wise man and endued with knowledge among you? Let him shew out of a good conversation his works with meekness of wisdom.
  — James 3:2,5,13
