צַו֮ אֶת־בְּנֵ֣י יִשְׂרָאֵל֒ וְנָתְנ֣וּ לַלְוִיִּ֗ם מִֽנַּחֲלַ֛ת אֲחֻזָּתָ֖ם עָרִ֣ים לָשָׁ֑בֶת וּמִגְרָ֗שׁ לֶֽעָרִים֙ סְבִיבֹ֣תֵיהֶ֔ם תִּתְּנ֖וּ לַלְוִיִּֽם׃
「你要吩咐以色列人,叫他們從所承受為業的產業中,把一些城分給利未人居住;城四周的郊野,你們也要分給利未人。
Mishnah Maaser Sheni
From here they said that Israelites and mamzerim may make the confession, but not converts, nor freed slaves, since they have no inheritance in the land. Rabbi Meir says: neither do priests and Levites since they did not take a share of the land. Rabbi Yose says: they have the Levitical cities.
