Levítico 25:33

And if a man purchase of the Levites. — Better, And if one of the Levites redeem it, that is, even if a Levite redeemed the house which his brother Levite was obliged to sell through poverty, the general law of house property is not to obtain even among the Levites themselves. They are to treat each other according to the law of landed property.

Then the house that was sold, and the city of his possession, shall go out. — Better, then the house that was sold in the city of his possession shall go out, that is, in the year of jubile the house is to revert to the vendor just as if it were landed property. Thus, for instance, the house of the Levite A, which he, out of poverty, was obliged to sell to the non-Levite B, and which was redeemed from him by a Levite C, reverts in the jubile year from the Levite C to the original Levitical proprietor A. It is, however, more than probable that the negative particle has dropped out of the text, and that the passage as it originally stood was, “And if one of the Levites doth not redeem it.” That is, if he does not act the part of the nearest of kin, then the house reverts in the year of jubile to the original Levitical owner, just as landed property. The Vulg. has still the negative particle.

For the houses of the cities of the Levites are their possession. — As these houses were all which the Levites possessed, they were as important to them as the land was to the other tribes, hence they were to be treated legally in the same way as the soil.
