Looking at Jewish texts to determine a Jew's level of obligation to help others
(ח) כִּ֤י תִבְנֶה֙ בַּ֣יִת חָדָ֔שׁ וְעָשִׂ֥יתָ מַעֲקֶ֖ה לְגַגֶּ֑ךָ וְלֹֽא־תָשִׂ֤ים דָּמִים֙ בְּבֵיתֶ֔ךָ כִּֽי־יִפֹּ֥ל הַנֹּפֵ֖ל מִמֶּֽנּוּ׃
(8) When you build a new house, you shall make a parapet for your roof, so that you do not bring bloodguilt on your house if anyone should fall from it.

אֶחָד הַגַּג וְאֶחָד כָּל דָּבָר שֶׁיֵּשׁ בּוֹ סַכָּנָה וְרָאוּי שֶׁיִּכָּשֵׁל בָּהּ אָדָם וְיָמוּת. כְּגוֹן שֶׁהָיְתָה לוֹ בְּאֵר אוֹ בּוֹר בַּחֲצֵרוֹ בֵּין שֶׁיֵּשׁ בּוֹ מַיִם בֵּין שֶׁאֵין בּוֹ מַיִם חַיָּב לַעֲשׂוֹת חֻלְיָא גְּבוֹהָה עֲשָׂרָה טְפָחִים. אוֹ לַעֲשׂוֹת לָהּ כִּסּוּי כְּדֵי שֶׁלֹּא יִפּל בָּהּ אָדָם וְיָמוּת. וְכֵן כָּל מִכְשׁל שֶׁיֵּשׁ בּוֹ סַכָּנַת נְפָשׁוֹת מִצְוַת עֲשֵׂה לַהֲסִירוֹ וּלְהִשָּׁמֵר מִמֶּנּוּ וּלְהִזָּהֵר בַּדָּבָר יָפֶה יָפֶה. שֶׁנֶּאֱמַר (דברים ד ט) "הִשָּׁמֶר לְךָ וּשְׁמֹר נַפְשְׁךָ". וְאִם לֹא הֵסִיר וְהֵנִיחַ הַמִּכְשׁוֹלוֹת הַמְּבִיאִין לִידֵי סַכָּנָה בִּטֵּל מִצְוַת עֲשֵׂה וְעָבַר בְּ(דברים כב ח) "לֹא תָשִׂים דָּמִים":
There is no difference between a roof or anything else that is dangerous and likely to cause death to a person who might stumble. If, for instance, one has a well or a pit in his courtyard — — he must build an enclosing ring ten handbreadths high, or put a cover over it, so that a person should not fall into it and die. So too, any obstruction that is a danger to life must be removed as a matter of positive duty and extremely necessary caution.
(לה) וְכִֽי־יָמ֣וּךְ אָחִ֔יךָ וּמָ֥טָה יָד֖וֹ עִמָּ֑ךְ וְהֶֽחֱזַ֣קְתָּ בּ֔וֹ גֵּ֧ר וְתוֹשָׁ֛ב וָחַ֖י עִמָּֽךְ׃

(35) And if your brother becomes poor, and
his means fail; then you should uphold him: as a stranger and a settler he should live with you

והחזקת בו. אַל תַּנִּיחֵהוּ שֶׁיֵּרֵד וְיִפֹּל וְיִהְיֶה קָשֶׁה לַהֲקִימוֹ, אֶלָּא חַזְּקֵהוּ מִשְּׁעַת מוֹטַת הַיָּד; לְמָה זֶה דוֹמֶה? לְמַשּׂאוֹי שֶׁעַל הַחֲמוֹר, עוֹדֵהוּ עַל הַחֲמוֹר אֶחָד תּוֹפֵס בּוֹ וּמַעֲמִידוֹ, נָפַל לָאָרֶץ, חֲמִשָּׁה אֵין מַעֲמִידִין אוֹתוֹ:

והחזקת בו You should uphold him — Do not leave him by himself so that he comes down in the world until he finally falls altogether when it will be difficult to give him a lift, but uphold him from the very moment of the failure of his means. To what may this (the differences between whether you assist him at once or whether you wait with your help till he has come down in the world) be compared? To an excessive load on the back of a donkey. So long as it is still on the donkey’s back, one person is enough to take hold of it (the load) and to keep it (the donkey) up, as soon as it has fallen to the ground not even five persons are able to set it on its legs (Sifra, Behar, Section 5 1).

The Dignity of Difference p. 30
David Hume noted that our sense o empathy diminishes as we move outward from the members of our
family to our neighbors, our society and the world. Traditionally, our sense of involvement with the fate
of others has been in inverse proportion to the distance separating us and them. What has changed is
that television and the Internet have effectively abolished distance. They have brought images of
suffering in far off lands into our immediate experience. Our sense of compassion for the victims of
poverty, war, and famine, runs ahead of our capacity to act. Our moral sense is simultaneously activated
and frustrated. We feel that something should be done, but what, how, and by whom?

איכא דמתני לה להא דרב הונא אהא דתני רב יוסף (שמות כב, כד) 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
There are those who teach that which Rav Huna said in connection with that which Rav Yosef taught: The verse states: “If you lend money to any of My people, even to the poor person who is with you” (Exodus 22:24). The term “My people” teaches that if one of My people, i.e., a Jew, and a gentile both come to borrow money from you, My people take precedence. The term “the poor person” teaches that if a poor person and a rich person come to borrow money, the poor person takes precedence. And from the term: “Who is with you,” it is derived: If your poor person, meaning one of your relatives, and one of the poor of your city come to borrow money, your poor person takes precedence. If it is between one of the poor of your city and one of the poor of another city, the one of the poor of your city takes precedence.
(יא) וַיְהִ֣י ׀ בַּיָּמִ֣ים הָהֵ֗ם וַיִּגְדַּ֤ל מֹשֶׁה֙ וַיֵּצֵ֣א אֶל־אֶחָ֔יו וַיַּ֖רְא בְּסִבְלֹתָ֑ם וַיַּרְא֙ אִ֣ישׁ מִצְרִ֔י מַכֶּ֥ה אִישׁ־עִבְרִ֖י מֵאֶחָֽיו׃

(11) Some time after that, when Moses had grown up, he went out to his kinsfolk and witnessed their labors. He saw an Egyptian beating a Hebrew, one of his kinsmen.

וירא בסבלתם. נָתַן עֵינָיו וְלִבּוֹ לִהְיוֹת מֵצֵר עֲלֵיהֶם (שמות רבה א'):
וירא בסבלתם AND HE SAW THEIR BURDENS — he set his eyes and mind to share in their distress. (Exodus Rabbah 1:27)
