Leviticus 25:35-37

35“ ‘If any of your fellow Israelites become poor and are unable to support themselves among you, help them as you would a foreigner and stranger, so they can continue to live among you. 36Do not take interest or any profit from them, but fear your God, so that they may continue to live among you. 37You must not lend them money at interest or sell them food at a profit.
