Easton's 1897 Bible Dictionary:

Swine
   (Heb. hazir), regarded as the most unclean and the most abhorred
   of all animals (Lev. 11:7; Isa. 65:4; 66:3, 17; Luke 15:15, 16).
   A herd of swine were drowned in the Sea of Galilee (Luke 8:32,
   33). Spoken of figuratively in Matt. 7:6 (see Prov. 11:22). It
   is frequently mentioned as a wild animal, and is evidently the
   wild boar (Arab. khanzir), which is common among the marshes of
   the Jordan valley (Ps. 80:13).
