바미드바르 (민수기) 35:4

אלף אמה סביב A THOUSAND CUBITS ROUND ABOUT — But afterwards, (v. 5) it says, “two thousand cubits”!? How can that be? They assign two thousand for them (for the Levites) round about their cities, and of these, the innermost thousand serves as the “open space” and the outermost is for fields and vineyards (Sotah 27b).

וּמִגְרְשֵׁי֙ הֶֽעָרִ֔ים אֲשֶׁ֥ר תִּתְּנ֖וּ לַלְוִיִּ֑ם מִקִּ֤יר הָעִיר֙ וָח֔וּצָה אֶ֥לֶף אַמָּ֖ה סָבִֽיב׃

And the open spaces of the cities, that you shall give to the Levites, shall reach from the wall of the city outwards a thousand cubits round about.
