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
(Leviticus 25:36,37) only, however, in their dealings with each other
(Deuteronomy 23:19,20) The violation of this law was viewed as a great crime
(Psalms 15:5; Proverbs 28:8; Jeremiah 15:10) After the Return, and later, this law was
much neglected
(Nehemiah 5:7,10)
