Tosefta for Ketubot 134:18

They may not give a poor person wandering from place to place less than a loaf worth a pundion at a time when four seahs [of wheat cost] one sela (see Peah 8:7, following Kulp Tr.). If he spends the night [at a place], they must give him the cost of what he needs for the night (ibid.), oil and pulse. If he stays over Shabbat they must give him enough food for three meals (ibid.), oil, pulse, fish, and vegetables. In what context does this apply? [It applies] when they know him, [in which case] they even clothe him (Y. Peah VIII.6.8). [But] if he [is someone who] is just going around to all the entrances [i.e., begging from door to door], they do not get involved with him in every thing (see Ketubot 67b:9).

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.).

[If a poor person] was accustomed to using golden vessels [and presumably still has the vessels but no money], he sells them and uses silver utensils. [If he was accustomed to] silver vessels, he sells them and uses copper vessels. [If he was accustomed to] copper vessels, he sells them and uses glass vessels. They said, a family of Beit Nevaltah was in Jerusalem that was descended from the sons of Ornan the Jebusite (see I Chron. 21:20). The Sages brought to them (or they brought to the Sages) six hundred golden shekels (שש not שלש per Erfurt manuscript, i.e., the amount David paid Ornan for his threshing-floor, the future site of the Temple, see I Chron. 21:25) but they did not want to take them outside of Jerusalem. [Note: Presumably, the family was now impoverished, and the Sages sought to return them to their previous status, indeed the status of their ancestor Ornan the Jebusite.]

One who says, "I shall not be provided for by others," [we nonetheless] persevere on him and we support him and [first] we give it to him as a loan, and we return and [then] we give it to him as a gift, the words of Rabbi Meier. Rabbi Shimon says, we say to him, "bring collateral," to give him the impression [that he is not receiving charity, see Ketubot 67b:9].
