Easton's 1897 Bible Dictionary:

Northward
   (Heb. tsaphon), a "hidden" or "dark place," as opposed to the
   sunny south (Deut. 3:27). A Hebrew in speaking of the points of
   the compass was considered as always having his face to the
   east, and hence "the left hand" (Gen. 14:15; Job 23:9) denotes
   the north. The "kingdoms of the north" are Chaldea, Assyria,
   Media, etc.
