Into swine ( words of Jesus )

Jesus cast out legion ( 4 to 6000 ) of demons into a herd of swine; ( Lev 11:7-8 ) says to the old testament Jewish law, they were unclean; Bible doesn't say why into pigs, but you have to consider pigs were considered unclean to Jews, that might have something to do with reason: ( Matt 8: 28-32 ) God bless
