Deuteronomy 15:4

Save when there shall be no poor among you; for the LORD shall greatly bless thee in the land which the LORD thy God giveth thee for an inheritance to possess it:

Save when there shall be no poor among you - apparently a qualifying clause added to limit the application of the foregoing statement; so that borrower; whereas it is implied that if he were rich, the restoration of the loan might be demanded even during that year. But the words may properly be rendered (as on margin) to the end, in order that there may be no poor among you - i:e., that none be reduced to inconvenient straits and poverty by unseasonable exaction of debts, at a time when there was no labour and no produce, and that all may enjoy comfort and prosperity, which will be the case through the special blessing of God on the land, provided they are obedient.
