Matthew 8:32 is the parallel account of the same event—demons enter pigs and the herd drowns.

Leviticus 11:7 declares pigs unclean; unclean spirits entering them is fitting because both are unclean.

Job 1:12 shows God giving Satan limited permission to harm Job; Jesus similarly permits the demons to enter the pigs.

John 8:44 calls the devil a murderer from the beginning; the demons' destructive act reflects their father's murderous nature.

1 Peter 5:8 warns the devil prowls seeking to devour; the demons destroying the pigs exemplifies this predatory destruction.

Revelation 9:11 names the demonic king Apollyon, 'Destroyer'; the demons' destruction of the pigs aligns with their king's title.
