Vayikra 25:33

‎הלוים‎ מן‎ואשר יגאל ‏ ‎‎‎ ‎— This means, and if any one buys a house or a city from them, then that house that has been sold or the city that was sold shall go out in the Jubilee and shall return unto the Levite who has sold it, and not be irredeemable as are other houses in “cities that have a wall” viz., those of Israelites. According to this explanation, יגאל has here the meaning of a “sale”. Another explanation is (taking יגאל here in its usual meaning of “redeeming”): Because it is stated in the previous verse: “the Levites shall have the right of redemption at any time”, I might think that Scripture is speaking only of an ordinary Israelite purchaser who bought a house in a city of the Levites, but when a Levite bought a house from another Levite it shall be irredeemable! Scripture therefore states “[the Levites shall have the right redemption at any time]”, ואשר יגאל מן הלוים, “also if one who redeems does so from the Levites — i. e. that also one (a Levite) who redeems a house from the possession of another Levite shall have the right to do so at any time (Sifra, Behar, Chapter 6 6). ויצא ממכר בית THEN THE HOUSE THAT WAS SOLD… SHALL GO OUT [IN THE JUBILEE] — According to the second explanation of ‎'ואשר יגאל וכו‎‎ given above, this contains another command and is not a continuation of the words that precede. They mean: “but if he (the vendor) did not redeem it” then it shall go out in the Jubilee and shall not become irredeemable at the end of the first year as is the case with the house of an Israelite. כי בתי ערי הלוים הוא אחזתם FOR THE HOUSES OF THE CITIES OF THE LEVITES ARE THEIR POSSESSION —They had no separate property of fields and vineyards, only cities to dwell therein together with the open land surrounding them; these, therefore, in their case took the place of the fields possessed by the Israelites and should thus be redeemable just like fields, in order that their inheritance should not be alienated from them.

וַאֲשֶׁ֤ר יִגְאַל֙ מִן־הַלְוִיִּ֔ם וְיָצָ֧א מִמְכַּר־בַּ֛יִת וְעִ֥יר אֲחֻזָּת֖וֹ בַּיֹּבֵ֑ל כִּ֣י בָתֵּ֞י עָרֵ֣י הַלְוִיִּ֗ם הִ֚וא אֲחֻזָּתָ֔ם בְּת֖וֹךְ בְּנֵ֥י יִשְׂרָאֵֽל׃

And if a man purchase of the Levites, then the house that was sold, and the city of his possession, shall go out in the year of jubilee: for the houses of the cities of the Levites are their possession among the children of Yisra᾽el.
