15 “This is what the Sovereign Lord says: The people of Philistia have acted against Judah out of bitter revenge and long-standing contempt. 16 Therefore, this is what the Sovereign Lord says: I will raise my fist of judgment against the land of the Philistines. I will wipe out the Kerethites and utterly destroy the people who live by the sea. 17 I will execute terrible vengeance against them to punish them for what they have done. And when I have inflicted my revenge, they will know that I am the Lord .”
