(36) Take thou no usury of him, or increase.--The first thing to be done to the impoverished Israelite is to supply him with the means to recover himself without any interest. The authorities during the second Temple defined the words which are translated "usury" (nesheck) and "increase" (tarbith, or marbith) as follows: If a person lends to another a shekel worth four denarii, and gets in return five denarii, or if he lends him two sacks of wheat, and receives back three, this is usury. If one buys wheat for delivery at the market price of 25 denarii a measure, and when it rises to 30 denarii he says to the vendor, "Deliver me the wheat, for I want to sell it and buy wine," and the vendor replies," I will take the wheat at 30 denarii and give thee wine for it," though he has no wine, this is increase. The "increase" lies in the fact that the vendor has no wine at the time, and that he may possibly lose again by the rise in wine. Accordingly the former is a charge upon money, whilst the latter is on products.

25:35-38 Poverty and decay are great grievances, and very common; the poor ye have always with you. Thou shalt relieve him; by sympathy, pitying the poor; by service, doing for them; and by supply, giving to them according to their necessity, and thine ability. Poor debtors must not be oppressed. Observe the arguments here used against extortion: Fear thy God. Relieve the poor, that they may live with thee; for they may be serviceable to thee. The rich can as ill spare the poor, as the poor can the rich. It becomes those that have received mercy to show mercy.Take thou no usury of him, or increase,.... Not only give him somewhat for his present relief, but lend him money to put him in a way of business, to get his living for the future, without requiring any interest for it; See Gill on Exodus 22:25,

but fear thy God; who has given this command, and expects to be obeyed; and who is good, and does good, and should be feared for his goodness' sake; and is omniscient, and knows what is secretly exacted, and will not suffer any exorbitance of this kind to pass unpunished:

that thy brother may live with thee; which it would be still more difficult for him to do, should usury and increase be taken of him.
