Jeremiah 47:4-7

4Because of the day that is coming To destroy all the Philistines And to cut off from Tyre and Sidon Every ally who remains. For the Lord is going to destroy the Philistines, The remnant [still surviving] of the coastland of Caphtor.

5Baldness [as a sign of mourning] will come on Gaza; Ashkelon will be cut off and ruined. O remnant of their valley, How long will you gash yourselves [as a sign of mourning]?

6O you sword of the Lord, How long will it be before you are quiet? Put yourself into your sheath; Rest and be still.

7How can His sword be quiet When the Lord has given it an order? Against Ashkelon and against the [whole Philistine] seashore There He has assigned it.”
