All the evils that men cause to each other because of certain desires, or opinions or religious principles, are rooted in ignorance. [All hatred would come to an end] when the earth was flooded with the knowledge of God.
MaimonidesFor it is said, "You shall strengthen the stranger and the dweller in your midst and live with him," that is to say, strengthen him until he needs no longer fall upon the mercy of the community or be in need.
