Pigs (swine) are frequently mentioned as a wild animal, and is evidently the wild boar (Arabic: khanzir), which is common among the marshes of the Jordan valley (Psalms 80:13).
Swine were regarded as the most unclean and the most abhorred of all animals (Leviticus 11:7; Isaiah 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 Matthew 7:6 (see Proverbs 11:22).
