I am invoking here the important question of whether and how to respond to a request for money by a beggar on the street.
I ask this question from the U.S., where, outside of Jewish neighborhoods, it can be reasonably (though not definitively) assumed that those asking for money are not Jewish. Though this situation is my primary focus, I am also interested in answers that may relate to what one does in Israel, or in Jewish communities.
I am not looking for piskei din as to whether "one should" (or, more likely, "one shouldn't") give. Instead, I am looking for answers which raise one or more Torah points that are relevant to the consideration.
A few which I had in mind:
-The prohibition of free gifts to "unfamiliar gentiles," and the exception to this prohibition relating to alms given "for the sake of peace"
-The law that one must give to one who explicitly proclaims he is hungry
-Law of leaving some grapes in one's vineyard and wheat in one's field for the poor "and the stranger"
-Deuteronomy 15:7-8: "For there will never cease to be needy people in your land, which is why I command you; open your hand to the poor and needy." (To me, "in your land" implies an extension to the non-Jewish needy; I am not sure, though.) (Reading this again, I think it must only be referring to the Land of Israel, and to ger toshavs there, i.e., when it is ours. BUT the fact that this verse seems to suggest it is OK to give to non-Jews in Israel may have general implications. [?])
-Ketuvot 68a: "If a person closes his eyes to avoid giving [any] charity, it is as if he committed idolatry."
-Gittin 61a: "We support the non-Jewish poor along with the poor of Israel."
-Considerations of middos, i.e. the question of being a certain type of person through a certain kind of action
-Very broadly speaking, issues of chilul/kiddush Hashem--that Jews should appear to others to be compassionate rather than cold or solipsistic people.
