When it is proper to act, do not use a word. Do not wish to speak first in the midst of a crowd. While it is a skill to speak, it is also a skill to be silent. It is better for you to be defeated while speaking the truth, than to be victorious through deceit. He who is victorious through deceit is defeated by the truth.
Untrue words are a characteristic of evil persons.
There has to be a great crisis before the lie is necessary. When there is someone, while you speak the truth, even if you lie there is no sin. Do not deceive anyone, especially him who needs advice. Wisdom leads the soul to the place of God. There is no kinsman of the truth except wisdom.
