Rabbi Sacks, z’l, cites 4 different verses that require us to be financially responsible for the well-being of our brothers. “Brothers” implies not just siblings and immediate or extended family, but the entire community. He cites Hosea, who describes God as a Parent, teaching a child to take its first steps. He then cites Maimonides’Laws of Charity, which include all of the entire Jewish community as well as those who attach themselves to it in the “brotherhood” of social responsibility.
