Leviticus 25:36

“Take thou no usury of him, or increase, etc.] 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 “<022225>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.”

“Of him - That is, of thy brother, whether he be Israelite, or proselyte. Or increase - All kinds of usury are in this case forbidden, whether of money, or of victuals, or of any thing that is commonly lent by one man to another upon usury, or upon condition of receiving the thing lent with advantage and overplus. If one borrow in his necessity, there can be no doubt but this law is binding still. But it cannot be thought to bind, where money is borrowed for purchase of lands, trade, or other improvements. For there it is reasonable, that the lender share with the borrower in the profit. Leviticus 25:39”

“25:36-37 The purpose of a loan was to help a poor person get back on their feet, not to make money from their vulnerability. Interest was forbidden on loans to Israelites but permitted on loans to foreigners (Deut 23:19-20).”
