מדרש אויף דברים 14:27

"and the Levite in your gates, for he has no portion or inheritance with you": Wherever you find the Levite, give him his portion (first-tithe). If he has no portion, he gives him poor-tithe. If he has no poor-tithe, he gives him peace-offerings.

"and the Levite who is in your gates": Wherever you find a Levite, give him his portion (first-tithe). If he has no portion, he gives him poor-tithe. If he has no poor-tithe, he gives him peace-offerings.

(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."
