Good Counsel

Phonetic: " Oy le'ze she'na'a'sa sa'nie'go'ro ka'te'go'ro. "

Translation: Beware he whose defending counsel became his prosecutor.

Meaning:

Knowing a friend becomes deeper the stronger the friendship is and the secrets of one friend are revealed to the other.
Occasionally, following conflicts and differences of opinions deriving from disputes over honor, money or lust, a friend can turn into an enemy.
This phrase is to remind us that even a good friend, i.e. our 'defending counsel' can become our 'prosecutor'.
Remembering this fact will help us confining our friendship. The Rule of Confinement will help us guarding both our friendship and ourselves in case of 'change of direction' the friendship may take!
