JER 47:5

5 [The people of] Gaza will be humiliated; they will shave off all the hair on their heads [to indicate that they are ashamed]. The [people of ]Ashkelon [city] will all be silent [because they will be mourning]. [All you people who live] along the coast [of the Mediterranean Sea] who are still alive, how long [RHQ] will you gash yourselves [because you are mourning]?”
