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]

A person who dwells in a city for thirty days is forced to give tzedakah to the Kupah (community fund that feeds the resident poor with a weekly food allocation) with the rest of the residents of the city. If he dwelt there three months they force him to give to the Tamhui (public soup kitchen for any hungry person). If he dwelt there six months they force him to give tzedakah for clothing to clothe the poor. If he dwelt there nine months they force him to give tzedakah for the burial fund which provides all the burial requirements for the poor.
