The phrase “daughters of the Philistines” is mentioned several times in Old Testament Scripture. It generally refers to all Philistine women. 2 Samuel 1:20 reads:
“Tell it not in Gath, proclaim it not in the streets of Ashkelon, lest the daughters of the Philistines be glad, lest the daughters of the uncircumcised rejoice.
So I stretched out my hand against you and reduced your territory; I gave you over to the greed of your enemies, the daughters of the Philistines, who were shocked by your lewd conduct.
Before your wickedness was uncovered. Even so, you are now scorned by the daughters of Edom and all her neighbors and the daughters of the Philistines—all those around you who despise you.
