Musar su Levitico 19:10

The fourth: To give charity (tsedekah) to the poor, the model of whom is Foundation and Kingship. And they have explained in the Tikkunim (Tikkun 18, p. 33a) that the charity that is fit for Them is to every day implement ninety [recitations of] amen, four [of] kedushah, one hundred blessings and five books of the Torah (as these numbers corresponds to the letters that spell out the word, tsedekah). And in this way, everyone [should] draw charity from Splendor to these Poor Ones. And he [should] procure for Them gleanings from all of the Sefirot, forgotten sheaves from the secret of the Highest Sheaf - which is Understanding - and the corner from the aspect of Kingship itself, as it is the corner for the other traits (it is the outermost Sefirah). It is written (Leviticus 19:10), "for the poor and the stranger shall you leave them" - as even Splendor is a stranger [when it is] below in Kingship, and one must give It from these reparations. And so [too, must one give] the poor tithe, to bring up Kingship, which is Tithe, to the Foundation, which is called the Poor. And if he connects it with Splendor, he will give from the Tithe to the Stranger. And several reparations are included in this.

וכרמך לא תעולל . The wording of the prohibition to pick your vineyard bare or to pick up fallen grapes (19,10) which is clearly designed to afford the poor a means of sustenance, carries a veiled warning not to chase away עוללים, people who spend all of their time studying Torah, when they come to the vineyard at harvest time to pick up their gleanings. In the final analysis it is Torah students such as these who ensure that the harvest of the vineyard will be successful, that G–d will direct His blessing onto our land.
