Valley of Sorek

Delilah was a woman living in the Valley of Sorek whom Samson loved. While the text doesn't explicitly call her a Philistine, she clearly sided with the Philistine lords who paid her 1,100 pieces of silver each to discover the secret of Samson's strength. Through persistent manipulation and emotional pressure, she eventually broke Samson down until he revealed that his strength came from his Nazirite vow, symbolized by his uncut hair.
