Easton's 1897 Bible Dictionary:

New Testament
   (Luke 22:20), rather "New Covenant," in contrast to the old
   covenant of works, which is superseded. "The covenant of grace
   is called new; it succeeds to the old broken covenant of works.
   It is ever fresh, flourishing, and excellent; and under the
   gospel it is dispensed in a more clear, spiritual, extensive,
   and powerful manner than of old" (Brown of Haddington). Hence is
   derived the name given to the latter portion of the Bible. (See TESTAMENT.)
