• Newari: “Woe to you who live side of the sea,
  people of Kerethite.
  The word of the LORD is against you,
  O Canaan, land of the Philistines,
  ‘I will destroy you,
  and no one will be there."” (Source: Newari Back Translation)
• Hiligaynon: “You (plur.) are-to-be-pitied Filistinhon who live in the seashore. This (is) what the LORD says against you (plur.): ‘You (plur.) Filistinhon in Canaan, I will-destroy you (plur.), and no-one will-be-left among you (plur.).’” (Source: Hiligaynon Back Translation)
