Tosefta su Pe'ah 8:7

We do not reduce [the agricultural gifts] to the poor during the years of of the poor person's tithe (i.e., the third and sixth years of the agricultural cycle) to less than half a kav of wheat or a kav of barley (Peah 8:5). In what context does this apply? [For grain that has been brought in to] the threshing floor, but [for grain brought] inside his house, we give [the poor person] any amount (כל שהו not כל שדהו), and we are not concerned [that it is too little]. And [similarly for] the remainder of the priestly gifts and the [gifts for the] Levite, we give any amount, and we are not concerned [that it is too little]. [If he is saving some to give to his poor relatives, see Peah 8:6], he can save half and give half. Abba Yosa ben Dostai said in the name of Rabbi Eliezer, "[If he] wants, he [can] place before [the poor people] a third and retain two-thirds for his [poor] relatives."

[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.

A poor person who gave a perutah (a small copper coin) to the communal fund and a piece of bread to the charity plate, we accept it from him. If he doesn't give, we don't require him to give. [If] they gave him new [clothes] and he returned to them [worn out] clothes, we accept it from him. If he didn't give [anything], we do not require him to give. [If] he was used to silk clothes, we give him silk clothes (cf. Y. Peah VIII.7.5). [If he was accustomed to having] a ma'ah (מָעָה not מטה, one-sixth of a denar/zuz, see Ket. 5:9, per Kulp), we give him a ma'ah; [similarly, if he is accustomed to having] dough, we give him dough, bread we give him bread, to be fed inside his mouth we feed him inside his mouth, as it says (Deut. 15:8), "[pledge to him (the needy one)] sufficient for his lack that is lacking to him (לו)." Even a slave, even a horse. "To him (לו)" -- this [refers to] a wife, as it says (Gen. 2:18), "I will make for him (לו) a help-mate opposite him." It so happened with Hillel the Elder, he obtained for a poor person of noble descent a horse upon which to ride and a servant to run in front of him (Ketubot 67b:3, Steinsaltz tr.). And moreover, it so happened with the people of the Galilee that they would bring a Sepphoris pound of meat to one old man every day (cf. Y. Peah VIII.7.4), Guggenheimer tr.).
