Easton's 1897 Bible Dictionary:

East
   (1.) The orient (mizrah); the rising of the sun. Thus "the east
   country" is the country lying to the east of Syria, the Elymais
   (Zech. 8:7).

     (2). Properly what is in front of one, or a country that is
   before or in front of another; the rendering of the word
   _kedem_. In pointing out the quarters, a Hebrew always looked
   with his face toward the east. The word _kedem_ is used when the
   four quarters of the world are described (Gen. 13:14; 28:14);
   and _mizrah_ when the east only is distinguished from the west
   (Josh. 11:3; Ps. 50:1; 103:12, etc.). In Gen. 25:6 "eastward" is
   literally "unto the land of kedem;" i.e., the lands lying east
   of Palestine, namely, Arabia, Mesopotamia, etc.
