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.
