Dimensions of the Universe of Obligation

From the American Jewish World Service Education Module on, "Addressing Global Poverty: International Aid, Debt Relief, and Trade Justice"

*Universe of Obligation is "the circle of individuals and groups toward whom obligations are owed, to whom rules apply, and whose injuries call for amends." (Accouting for Genocide, Helen Fein, Free Press, 1979, p. 4)

-What do each of these texts suggest about the dimensions of our universe of obligation? What do they say about how we should prioritize among claims of obligation?

Babylonian Talmud, Baba Metzia 71a
דתני רב יוסף (שמות כ"ב) אם כסף תלוה את עמי את העני עמך, עמי ונכרי - עמי קודם, עני ועשיר - עני קודם, ענייך ועניי עירך - ענייך קודמין, עניי עירך ועניי עיר אחרת - עניי עירך קודמין.
R. Joseph learnt: If you lend money to any of my people that are poor with you: [this teaches, if the choice lies between] a Jew and a non-Jew, a Jew has preference; the poor or the rich the poor takes precedence; your poor [i.e. your relatives] and the [general] poor of your town, your poor come first; the poor of your city and the poor of another town the poor of your own town have prior rights. [Soncino translation]
Babylonian Talmud, Gittin 61a
ת"ר: מפרנסים עניי נכרים עם עניי ישראל, ומבקרין חולי נכרים עם חולי ישראל, וקוברין מתי נכרים עם מתי ישראל, מפני דרכי שלום.
Our Rabbis taught: We sustain the non-Jewish poor with the Jewish poor, visit the non-Jewish sick with the Jewish sick, and bury the non-Jewish dead with the Jewish dead, for the sake of peace. [AJWS translation]
