(34) But the field of the suburbs of their cities may not be sold.--The Levitical cities had both suburbs or commons for their cattle, &c, and fields which they cultivated (Numbers 35:4-5). These outlying fields, which were beyond the suburbs, they are here forbidden to sell. According to the authorities during the second Temple the expression "to sell" here used is to be taken in a wider sense as including diverting any part of it from its original purpose. Hence they say it forbids the Levites not only to sell the field, but to convert it into a suburb, and vice versa. What is field must always remain field, what is suburb must remain suburb, and what is city must continue to be city.

For it is their perpetual possession.--The estates belong to the whole tribe to all futurity, and the present occupiers have to transmit them intact to their successors. Hence no present owner, or all of them combined, have a right to dispose of any portion of the estates, or materially to alter it. They must hand these estates down to their successors as they receive them from their predecessors.

25:23-34 If the land were not redeemed before the year of jubilee, it then returned to him that sold or mortgaged it. This was a figure of the free grace of God in Christ; by which, and not by any price or merit of our own, we are restored to the favour of God. Houses in walled cities were more the fruits of their own industry than land in the country, which was the direct gift of God's bounty; therefore if a man sold a house in a city, he might redeem it only within a year after the sale. This encouraged strangers and proselytes to come and settle among them.But the field of the suburbs of their cities may not be sold,.... The suburbs to the cities of the Levites reached two thousand cubits on every side of their cities, Numbers 35:5; in which they had fields to keep their cattle in, and these belonged to them in common; every Levite had not a particular field to himself as his own property, and which is the reason why it might not be sold, nor might they agree together to sell it, for then they would have nothing to keep their cattle in: the Jewish writers generally understand this of changing their fields, suburbs, and cities: hence they say, in the Misnah, they do not make a field a suburb, nor a suburb a field, nor a suburb a city, nor a city a suburb; upon which Maimonides (o) says, all agree that the Levites may not change a city, or suburb, or field which are theirs, because of what is said, Leviticus 25:34; and the wise men, of blessed memory, say, the meaning of it is, it shall not be changed, for they do not change anything from what it was before:

for it is their perpetual possession: and therefore never to be alienated from them, or be sold to another, or changed and put to another use; such care was taken of the ministers of the sanctuary, and of their maintenance and support, under the former dispensation; and suggests that they should continue in their stations without any alteration, as ministers of the Gospel should, who ought to give up themselves to the ministry of the word, and prayer, and not entangle themselves with the affairs of life.
