Ezekiel 25:15-17 RSV

15 "Thus says the Lord GOD: Because the Philistines acted revengefully and took vengeance with malice of heart to destroy in never-ending enmity;
16 therefore thus says the Lord GOD, Behold, I will stretch out my hand against the Philistines, and I will cut off the Cher'ethites, and destroy the rest of the seacoast.
17 I will execute great vengeance upon them with wrathful chastisements. Then they will know that I am the LORD, when I lay my vengeance upon them."
