Jeremiah 47:4-7

4For the day has come to destroy all the Philistines and to remove all survivors who could help Tyre and Sidon. The Lord is about to destroy the Philistines, the remnant from the coasts of Caphtor. 5Gaza will shave her head in mourning; Ashkelon will be silenced. You remnant on the plain, how long will you cut yourselves? 6“ ‘Alas, sword of the Lord, how long till you rest? Return to your sheath; cease and be still.’ 7But how can it rest when the Lord has commanded it, when he has ordered it to attack Ashkelon and the coast?”
