Musar do Rodzaju 6:17

The Zohar in its commentary on this פרשה, warns repeatedly that one must be careful not to expose oneself to danger at a time when danger lurks all around. We have discussed the letter מ as alluding to the angel of death. As long as the angel of death does not come face to face with a potential victim he has no control over such a person. It is best to hide in one's house during wars and other times when violence erupts, so as not to expose oneself to the forces of destruction.
