4For the day has come
to destroy all the Philistines,
to cut off from Tyre and Sidon
every remaining ally.
Indeed, the LORD is about to destroy the Philistines,
the remnant from the coasts of Caphtor.
5The people of Gaza will shave their heads in mourning;
Ashkelon will be silenced.
O remnant of their valley,
how long will you gash yourself?
— Jeremiah 47:4-5
