Notwithstanding the cities of the Levites, and the houses of the cities of their possession, may the Levites redeem at any time.

The houses of Levites, which are in cities, may always be redeemed:

But as to the cities of the Levites, the houses in the cities of their possession, the Levites shall have a perpetual right of redemption.

As to cities of the Levites, houses of the cities of their possession, redemption age-during is to the Levites;

But the houses in the towns of the Levites may be got back by the Levites at any time.

'Nevertheless the cities of the Levites, the houses in the cities of their possession, the Levites may redeem forever.

The buildings of the Levites, which are in the cities, are always able to be redeemed.

Urbium autem Levitarum, et domorum urbium possessionis eorum, redemptio perpetua erit Levitis.

Notwithstanding the cities of the Levites. Another exception, that the Levites should recover the houses they had sold, either by the right of redemption, or gratuitously in the year of jubilee. And this is not only appointed out of favor to them, but because it concerned the whole people, that they should be posted like sentries in the place which God had assigned to them. As to the suburbs, or the lands destined for the support of their cattle, God forbids their alienation, because thus they would have forsaken their proper station and removed elsewhere; whereas it was of importance to the whole people that such a dispersion should not occur.

Rather, And concerning the cities of the Levites, the houses in the cities of their possession, etc. If one of the Levites redeems a house in the city, etc. The meaning appears to be, if a Levite redeemed a house which had been sold to a person of a different tribe by another Levite, it was to revert in the Jubilee to the latter Levite as its original possessor. The purchaser of a Levite's house was in fact only in the condition of a tenant at will, while the fields attached to the Levitical cities could never be alienated, even for a time.
For the application of the law of Jubilee to lands dedicated to the service of the sanctuary, see Leviticus 27:16-25.

The cities of the Levites - The law in this and the following verses was also a very wise one. A Levite could not ultimately sell his house: if sold he could redeem it at any time in the interim between the two jubilees; but if not redeemed, it must go out at the following jubilee. And why? "Because Moses framed his laws so much in favor of the priesthood, that they had peculiar privileges?" etc. Just the reverse: they were so far from being peculiarly favored that they had no inheritance in Israel, only their cities, to dwell in: and because their houses in these cities were the whole that they could call their own, therefore these houses could not be ultimately alienated. All that they had to live on besides was from that most precarious source of support, the freewill-offerings of the people, which depended on the prevalence of pure religion in the land.

Notwithstanding, the cities of the Levites,.... The six cities of refuge, and forty two others; these and the houses in them are excepted from the above law, and only they; not such as they might purchase elsewhere; wherefore it follows:
and the houses of the cities of their possession; which were in cities possessed by them, and which was their possession, and given them as such:
may the Levites redeem at any time; they were not restrained to a year, as houses in walled towns, but they might redeem them as they pleased or could; and if they did not redeem them within the year, they might redeem them afterwards, even years after, and any time before the year of jubilee; so it is said in the Misnah (l) the priests and the Levites sell always, and they redeem always, as it is said, Leviticus 25:32; on which one of the commentators says (m) "they sell always", not as the Israelites, who cannot sell less than two years before the jubilee; but the Levites can sell near the jubilee: "and they redeem always"; if they sell houses in walled cities, they are not confirmed at the end of the year, as the houses of Israelites; and if they sell fields, it is not necessary they should remain in the hands of the buyer two years, but they may redeem them immediately if they will: this redemption was peculiar to the Levites; for if an Israelite has an inheritance from his father's mother, a Levite, he might not redeem according to the manner Levites did, but according to Israelites; and so a Levite that inherited from his father's mother, an Israelite, was obliged to redeem as an Israelite and not as a Levite (n); for this perpetual redemption respected only houses that were in the cities of the Levites.

Notwithstanding the cities of the Levites, &c.--The Levites, having no possessions but their towns and their houses, the law conferred on them the same privileges that were granted to the lands of the other Israelites. A certain portion of the lands surrounding the Levitical cities was appropriated to them for the pasturage of their cattle and flocks (Numbers 35:4-5). This was a permanent endowment for the support of the ministry and could not be alienated for any time. The Levites, however, were at liberty to make exchanges among themselves; and a priest might sell his house, garden, and right of pasture to another priest, but not to an Israelite of another tribe (Jeremiah 41:7-9).

On the other hand, so far as the Levitical towns, viz., the houses of the Levites in the towns belonging to them, were concerned, there was to be eternal redemption for the Levites; that is to say, when they were parted with, the right of repurchase was never lost. עולם (eternal) is to be understood as a contrast to the year allowed in the case of other houses (Leviticus 25:29, Leviticus 25:30).
