너희 중에 분깃이나 기업이 없는 레위인과 네 성중에 우거하는 객과 및 고아와 과부들로 와서 먹어 배부르게 하라 그리하면 네 하나님 여호와께서 너의 손으로 하는 범사에 네게 축복을 주시리라
Ibn Ezra
At the boundary of seven years you will arrange a release denotes the beginning of the year, as is corroborated by the passage of “assemble the people” [31: 12]. The passage is connected to the previous one because, having mentioned that the Pauper’s Tithe belongs to the Levite, and the alien, and the orphan, and the widow [cf. 14: 29], it is now logical to discuss the general release. release [Hebrew: shmiṭṭah] from “drop her” [Hebrew: shimṭuhah] [II Kings 9: 33]: i.e., they released her, and she fell.

הלקט והשכחה והפאה וההפקר – are exempt from the tithes, as it is written (Deuteronomy 14:29): “Then the Levite, who has no hereditary portion as you have…,” from what you have and what he lacks, you are obligated to give to him, excluding those who have what you have with you.
Bartenura
Concerning that which is הפקר/ownerless, it is written (Deuteronomy 14:29): “Then the Levite, who has not hereditary portion as you have….” from what you have and that he lacks, you are required to give, excluding that which is ownerless, for both your hand and his hand are equivalent [concerning this].
