Usury
the sum paid for the use of money, hence interest; not, as in the modern sense, exorbitant interest. The Jews were forbidden to exact usury (Lev. 25:36, 37), only, however, in their dealings with each other (Deut. 23:19, 20). The violation of this law was viewed as a great crime (Ps. 15:5; Prov. 28:8; Jer. 15:10). After the Return, and later, this law was much neglected (Neh. 5:7, 10).
