Le Deutéronome 14:27 Midrash : Sifrei Devarim

וְהַלֵּוִ֥י אֲשֶׁר־בִּשְׁעָרֶ֖יךָ לֹ֣א תַֽעַזְבֶ֑נּוּ כִּ֣י אֵ֥ין ל֛וֹ חֵ֥לֶק וְנַחֲלָ֖ה עִמָּֽךְ׃ (ס)

Et le Lévite qui sera dans tes murs, tu ne le négligeras pas, car il n’a point de part ni de patrimoine comme toi.

Sifrei Devarim

(Devarim 14:27) "And the Levite who is in your gate, you shall not forsake him" (by not giving him first tithe): Wherever you find this Levite, give him of his portion (first-tithe). If he does not have his portion, he gives him second-tithe. If he does not have second-tithe, he gives him poor-tithe. If he does not have poor-tithe, he gives him peace-offerings. If he does not have peace-offerings, he feeds him from charity, it being written (26) "you … (27) and the Levite."
