“Notwithstanding the cities of the Levites, and the houses of the cities of their possession, may the Levites redeem at any time.”
King James Version (KJV)
25:30 It shall not go out - The reasons before alledged for lands do not hold in such houses; there was no danger of confusion in tribes or families by the alienation of houses. The seller also had a greater propriety in houses than in lands, as being commonly built by the owner's cost and diligence, and therefore had a fuller power to dispose of them. Besides, God would hereby encourage persons to buy and possess houses in such places, as frequency and fulness of inhabitants in cities, was a great strength, honour and advantage to the whole land.
25:31 In the villages - Because they belonged to and were necessary for the management of the lands.
25:34 May not be sold - Not sold at all, partly, because it was of absolute necessity for them for the keeping of their cattle, and partly because these were no enclosures, but common fields, in which all the Levites that lived in such a city had an interest, and therefore no particular Levite could dispose of his part in it.
