Leviticus 25:35-37

35‘Now if your fellow countryman becomes poor and his hand falters with you [that is, he has trouble repaying you for something], then you are to help and sustain him, [with courtesy and consideration] like [you would] a stranger or a temporary resident [without property], so that he may live among you.

36Do not charge him usurious interest, but fear your God [with profound reverence], so your countryman may [continue to] live among you.

37You shall not give him your money at interest, nor your food at a profit.
