Leviticus 25:33
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 jubile: for the houses of the cities of the Levites are their possession among the children of Israel.
And if a man purchase of the Levites,.... An house or city, as Jarchi, and which the following clause confirms, that is, if a common Israelite made such a purchase, then it was redeemable, but if a Levite purchased of a Levite, then, as the same writer observes, it was absolutely irredeemable:
then the house that was sold, and the city of his possession, shall go out in the year of jubilee; to the original owner of it, as fields and houses in villages sold by the Israelites
for the houses of the cities of the Levites are their possession among the children of Israel; and their only possession, and therefore if those, when sold, were irredeemable, they would entirely be without any; and hence care is taken they should not; so Jarchi observes, that the Levites had no possession of fields and vineyards, only cities to dwell in, and their suburbs; wherefore cities were to them instead of fields, and their redemption was as that of fields, that so their inheritance might not be broken off from them.
