וְעָרֵי֙ הַלְוִיִּ֔ם בָּתֵּ֖י עָרֵ֣י אֲחֻזָּתָ֑ם גְּאֻלַּ֥ת עוֹלָ֖ם תִּהְיֶ֥ה לַלְוִיִּֽם׃
But as for the cities of the Levites, the houses of the cities of their possession, the Levites shall have a perpetual right of redemption.
Targum Jonathan on Leviticus
But the cities of the Levites, the houses of the cities of their possession may be always redeemable by the Levites.
