Comentario sobre Levítico 25:32

וערי הלוים THE CITIES OF THE LEVITES… [MAY BE REDEEMED AT ANY TIME] — This refers only to the forty-eight cities which had been given to them (cf. Numbers 35:6. 7). (But if the Levites built another city for themselves, or if a Levite possesses a house in a city inhabited by Israelites these do not come under this law).

גאולת עולם תהיה ללוים, “the Levites will have an unlimited period during which to redeem their houses.” It does not matter if these houses are part of a walled city or of open villages, they are never sold in perpetuity, seeing that they are the only ancestral property the Levites own in the Holy Land as spelled out clearly in Numbers 35,3: והיו הערים להם לשבת ומגרשיהם יהיו לבהמתם ולרכושם ולכל חיתם,” and they shall have these cities to dwell in, and their open land shall be for their cattle and for their substance and for all their beasts.”

גאלת עולם [THE LEVITES SHALL HAVE] THE RIGHT OF REDEMPTION AT ANY TIME — This means that they (Levites) may redeem at once — even before the end of two years — if they sold a field of those fields which had been given to them within the two thousand cubits round about the cities (cf. Numbers 25:5) (whilst an ordinary Israelite’s field must remain at least two years in the hand of the purchaser), or if they sold “a house in a city which has a wall” they may redeem it at any time and it does not become irredeemable at the end of one year (as is the case with such houses belonging to Israelites; cf. v. 30) (Arakhin 33b).
