Tosefta for Bava Batra 16:19

[We give to the poor from] the charity dish the whole day. [And we give the to poor from] the communal fund from Sabbath eve to Sabbath eve. [We give from] the charity dish to every person, [and from] the communal fund to people from the same town. If [a particular poor person] was there for thirty days, behold, he is like the people of the town [for purposes of] the communal fund, and [we provide him] clothing for six months. [However], to the poor people of the city [we provide] clothing for twelve months.
