Does the Tora realy mean Money; it seems that not. The legaly archetype subject of a loan were seeds. As the harvest depends on rain and labor and bracha from haSchem, the creditor is prohibited to exert force on the debitor, to participate in haShem’s bracha which was not for him but for others. However the interest rate for money is the risk premium for debitors default, which is independend from haSchem.
