37 You must not lend them money at interest or sell them food at a profit.

Matthew Henry's Commentary on Leviticus 25:37

Commentary on Leviticus 25:35-38

(Read Leviticus 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.

19 Do not charge a fellow Israelite interest, whether on money or food or anything else that may earn interest.

Matthew Henry's Commentary on Deuteronomy 23:19

Commentary on Deuteronomy 23:15-25

(Read Deuteronomy 23:15-25)

It is honourable to shelter and protect the weak, provided they are not wicked. Proselytes and converts to the truth, should be treated with particular tenderness, that they may have no temptation to return to the world. We cannot honour God with our substance, unless it be honestly and honourably come by. It must not only be considered what we give, but how we got it. Where the borrower gets, or hopes to get, it is just that the lender should share the gain; but to him that borrows for necessary food, pity must be showed. That which is gone out of thy lips, as a solemn and deliberate vow, must not be recalled, but thou shalt keep and perform it punctually and fully. They were allowed to pluck and eat of the corn or grapes that grew by the road side; only they must not carry any away. This law intimated what great plenty of corn and wine they should have in Canaan. It provided for the support of poor travellers, and teaches us to be kind to such, teaches us to be ready to distribute, and not to think every thing lost that is given away. Yet it forbids us to abuse the kindness of friends, or to take advantage of what is allowed. Faithfulness to their engagements should mark the people of God; and they should never encroach upon others.

20 You may charge a foreigner interest, but not a fellow Israelite, so that the Lord your God may bless you in everything you put your hand to in the land you are entering to possess.
