 A more mutually profitable arrangement existed in Sumerian law, by which a lender and a debtor make contractual arrangements to become partners in a business venture, with the lender agreeing to invest in the venture, and the debtor agreeing to manage the venture; the bond thus has characteristics of both a loan and a trust, as the lender's financial share in the venture is effectively the return on the loan, and the debtor's financial share in the venture is effectively a wage.The Code of Hammurabi contains regulations attempting to govern the use of these contracts.The Mishnah carefully tries to prevent evasion of the scriptural injunction against usury, preferring to forbid "moral usury" to trying to mitigate the scriptural rules in this area.
