And if the man have none to redeem it
That is, none of kin that was able or willing to redeem it; otherwise no doubt there were persons in the land able to do it at any time, but none he was in connection with, or from whom he could expect such a favour:
and himself be able to redeem it;
or if his hand has got, and he has found a sufficiency for his redemption, as the Targum of Jonathan; not that he has found anything that was lost, as Chaskuni glosses it, but by one providence or another, by the blessing of God on his trade and business, is become rich, and it is in the power of his hand to redeem the possession he had sold, he might do it; but, as the same writer observes, he might not borrow and redeem, but must do it with what he had got of his own since the time of sale, and which is also the sense of others F4.
