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.
