Deuteronomy 12:19

השמר לך TAKE HEED TO THYSELF [LEST THOU FORSAKE THE LEVITE] — This is intended in addition to the positive command expressed in the previous verse, to attach to it (the neglect of the Levite) a negative command, also. על אדמתך [TAKE HEED TO THYSELF LEST THOU FORSAKE THE LEVITE] UPON THY GROUND — but in exile (outside the Holy Land) you are not admonished as regards him more than as regards the poor of the ordinary Israelites (Sifrei Devarim 74:9; Talmud Yerushalmi Horayot end).

הִשָּׁ֣מֶר לְךָ֔ פֶּֽן־תַּעֲזֹ֖ב אֶת־הַלֵּוִ֑י כׇּל־יָמֶ֖יךָ עַל־אַדְמָתֶֽךָ׃ {ס}        

Take heed to thyself that thou forsake not the Levite as long as thou livest upon the earth.
