Matthew Henry Commentary Leviticus 25:35-38

"And if thy brother be waxed poor, and his hand fail with thee; then thou shalt uphold him: [as] a stranger and a sojourner shall he live with thee. Take thou no interest of him or increase, but fear thy God; that thy brother may live with thee. Thou shalt not give him thy money upon interest, nor give him thy victuals for increase. I am Jehovah your God, who brought you forth out of the land of Egypt, to give you the land of Canaan, [and] to be your God." — Leviticus 25:35-38 (ASV)

Poverty and decay are great grievances, and very common; you have the poor always with you. You are to relieve him: by sympathy, pitying the poor; by service, doing for them; and by supply, giving to them according to their necessity and your 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 you.

The rich can hardly do without the poor, just as the poor can hardly do without the rich. It is fitting for those who have received mercy to show mercy.
