If there be among you a needy person, one of your brothers, within any of your gates in your land that Hashem your God is giving you, you shall not harden your heart and you shall not shut your hand from your needy brother.
English: "Within any of your gates" — this teaches that the residents of your own city take precedence over the residents of another city, and that if a person is already going from door to door you are not obligated to him.
On the daf / in context: Local poor have priority; a professional beggar who systematically collects is not the primary responsibility of any single householder.
Type of Learning
Derash on the verse (Sifrei) — local poor take priority; door-to-door collectors are secondary.
What Is Learned
The poor of one’s own city take precedence over the poor of another city; one is not primarily obligated to a person who systematically collects from door to door.
