Community

The Rabbis teach: When Israel is in trouble and a Jew separates himself, two angels accompany that person and place their hands on his head.  They say, 'This man has separated himself from the community will not see its redemption.'
It is further taught: If the community is in trouble, a person must not say, 'I will go home, eat and drink and have peace in my soul.'  Each person must share int he burdens of the community as did Moshe Rabbenu.  The one who shares its turmoil will live to its its redemption. - Taanit

Our responsibility is always to assist one another.  We are charged by God and blessed by His emissaries to always be a part of k'llal Yisrael.
