'Backbiting' in the Bible

For I am afraid that perhaps when I come I may not find you to be what I desire, and that you may find me to be what you do not desire; that perhaps there may be contention, jealousy, bitter feeling, party spirit, ill-natured talk, backbiting, undue eulogy, unrest;

The north wind driveth away rain: so doth an angry countenance a backbiting tongue.
