For the seller shall not return - In the sale of all heritages among the Jews, it was always understood that the heritage must return to the family on the year of jubilee, which was every fiftieth year; but in this case the seller should not return to possess it, as it was not likely that he should be alive when the next jubilee should come, and if he were even to live till that time, he could not possess it, as he would then be in captivity. And the reason is particularly given; for the vision - the prophetic declaration of a seventy years' captivity, regards the whole multitude of the people; and it shall not return, i.e., it will be found to be strictly true, without any abatement.
Although they were yet alive - Though they be yet among the living.
Which shall not return - He (i. e. the seller) shall not return; and, every man living in his iniquity, they shall gather no strength. Exile being the punishment of iniquity, the exiles were said to “live in their iniquity.”
